Osprey Stratos 24 Reviews:

Positive Reviews:

I bought this pack to facilitate running to work (4.5 miles one way) on the weeks that I am on call and have to take my laptop home with me. My requirements were that I needed a pack that would allow me to strap my laptop securely to my body to minimize bouncing and yet allow me to run relatively comfortably.
We are a single-car family. My normal mode of operation is to have my wife drop me off at work on Monday with clothing and food for the week. Then, I run to and from work during the week and on Friday she picks me up after work so that I can take home my dirty clothes and empty food containers to prepare for the next week. For normal weeks, I only carry a small fanny pack to and from work -- enough to hold my ID badge and one or two small items. My job requirements recently changed such that one week out of five I will be on call and will need to take my laptop computer home with me each night. I purchased this pack after my running consistency was wrecked during the first week that I was on call. Though I have yet to have a turn in the pager rotation since I bought the pack, I have used it twice to commute and once just as a test running from home.
For running, I find that trying to fit the pack as recommended does not work for me. With the hip belt resting on my hips, there was too much bouncing and after I adjusted the shoulder straps to reduce the bouncing, the hip belt was resting well above my hips. I just snugged it up where it rested and it seems to work well. My pack is a medium. I thought of returning it for a large sized pack, but I think that I would still have the hip belt pulled up off of my hips and this one should be sized appropriately if I ever use it for hiking.
Positives:
* It works. I am able to run the 4.5 miles between work and home with my laptop with minimal bouncing once I get the straps adjusted. I do sometimes have to readjust straps while en route, but that is easy to do. It is great that I won't have my training disrupted so much the next time that I'm carrying the pager and that I won't need to get a ride home when I occasionally have to bring my laptop home for some after-hours work.
* Compression straps. The compression straps hold the laptop securely to prevent bouncing.
* AirSpeed suspension. I really like this. Though I do get warmer wearing the pack, I sometimes feel a refreshing breeze blow across my back. Very nice.
* Rain cover. Though I have not used it, I appreciate the fact that it has an integrated rain cover in the event that I get caught in the rain between home and work.
Negatives:
* The Stow on the Go trekking pole attachment on the left shoulder strap rubbed the inside of my arm a couple of times when I was reaching to adjust straps or wipe sweat from my brow. It seemed like something that could cause chafing if I ever did decide to run farther than 4.5 miles. Since I will never be using trekking poles, I cut it off. Problem solved.
This pack definitely allows me to do what I want to do even though "running commute" is not listed among the recommended uses. Personally, I would recommend that a person try to avoid running with a backpack if possible because it is simply nicer to run without one. If, however, you cannot avoid it, I think that this pack can work well.

Awesome daypack

This is the most comfortable daypack I have ever tried and I have been searching for one all summer. I will compare this pack to two others that I bought and returned at REI, the REI venturi 30 and the Mountain Hardwear fluid 26. I'll talk about these bags first and their downfalls and then about the Osprey Stratos 24 and why it's leaps and bounds ahead of the rest. The REI Venturi 30 daypack seemed like a really nice and modestly priced daypack. I tried it on and it seemed to fit nice in the store. The suspension system was well thought out with the mesh back panel for ventilation and decent waist belt. The day after I purchased it I went for a 4 mile hike and I soon realized that the pack was about an inch short on the torso length even though I got the large. I'm 6' tall so I'm not out of normal size ranges and the pack was still riding really high on my waist. I had maybe 15 pounds of gear and water. The bag also lacked good compression, it was very sloppy when moving quickly. I returned the pack the next day and order the Mountain Hardwear fluid 26 online. Mountain Hardwear fluid 26 was great on paper. It had the correct torso lenth I needed and seemed like a great all around daypack with lots of pockets for organization. When I picked up the pack at REI I immediatly knew that I would eventually return it. There is no structure to this pack what so ever. There is a corrugated plastic sheet that's suppose to add stability but it folded like a wet paper bag. After researching daypacks again, I decided to try the Osprey Stratos 24.The Osprey Stratos 24 is the ultimate daypack. The suspension is awesome. It has the mesh back panel similar to the Venturi 30 which keeps your back dry even in the sweltering summer months. The hipbelt is so much more comfortable than the Venturi 30 and the torso length is perfect for me (size large) again I am 6'. The size of the pack is perfect too. Enough room for all the essentials and nothing more. The hipbelt pockets are really big and fit my sunglasses and IPhone no problem. The hydration pocket can fit up to 100oz bladders if I'm not mistaken and it has a loop or a quick clip to hang any style of bladder. The side pockets are on the skinny side and I couldn't fit a standard 32oz nalgene bottle in them but they are accessible while moving. There is a small pocket on the shoulder straps that could fit a small cell phone or GPS unit, it will not fit an IPhone or similar device. The zipper pulls are nice and easily manipulated even with gloves on. The bag also comes with a built-in rain cover.This bag is a must-have for a daypack. The price is right and the features are outstanding. I am becoming a huge Osprey pack fan.

Passed my RAGBRAI test

So I just finished RAGBRAI 2010 with this thing... and I LOVE it! That's 500+ biking miles in 7 days, 70-95F temps, a lot of hydration refills, and one very rainy/cold 4-hour morning. And the thing that impressed me the most was the lack or almost lack of a concentrated wet spot on my back on those hot days.

I was seriously excited about that! You cyclists know exactly what I'm talking about, considering all those venting claims made by pack manufacturers about miniscule channels in their padding design. The venting on this thing is huge by comparison.

From that experience, I have some tips/tricks for you if you decide to get this or test it for yourself:

1) If you're biking road distance (as opposed to MTB), keep the waist straps correctly mounted across your hip bones BUT loosen the shoulder straps and the chest strap about 1-2 inches each. That'll get you some comfy play when you go into your riding crouch, and gravity will do the rest to keep things stable.

2) At road speed in the rain, really make sure that the rain cover is especially secure around the top corners and across the top. I had a tiny gap across the top during the start of the storm and found that it was enough to let quite a bit of water through to the pack. If I had been standing still, the gap wouldn't have been an issue but 15mph+ in a storm, it's a different ballgame. However, very little got into the pack because the pack material resisted the water that got through the cover very well. Unfortunately, enough got through before I fixed it to run the ink on my route maps.

3) Try not to use a Camelbak bladder. It's tempting if you already have one. I know because I brought both a Camelbak AND the 3L Osprey bladder. It's not that the former are deficient but rather it's a pack design thing. You'll need a bit of manipulative force to get a full bladder into the pack pouch and the hard shell on the Osprey bladder makes this easier.

4) The reinsertion of the hydration bladder takes a bit of a learning curve, but I found that it became comfortable very quickly (i.e. by the 3rd refill). The hard edge of the Osprey bladder catches on the first of two crosswires that give you that fantastic ventilation. I solved that by using one hand to push the bladder into its pouch while putting my other hand in the venting space and pushing the bladder clear of the wire as it gets close. It got easy very quickly but expect some jostling the first couple of times.

I used the pack 6 entire days out of the 7 and couldn't stop talking about it.

Exactly what I needed and expected

I decided to upgrade my hot, stuffy camera-specific daypack to something more modern, lighter and cooler. For two weeks I surfed, studied, obsessed, plotted and charted a side-by-side comparison of the Osprey Stratos 24, Syncro 20, Manta 25 and Talon 22. I finally settled on the Stratos 24 with absolutely no regrets.The Talon was out because it doesn't have the framed airspeed suspension or integrated rainfly – I hike, mostly, in hot, humid weather with frequent pop-up thunderstorms.The Syncho has the airspeed frame but lacks harness pockets and hipbelt pockets. I'd like to be able to get to something, even something little, without always having to remove the pack.The tie-breaker with the Manta 25 was the Stratos' much heavier fabric (210D double ripstop nylon and 420HD nylon pack cloth versus 70x140 nylon shadow creek) and beefier harness. This translates to a heavier load capacity for the Stratos of about five additional pounds. The ice axe tool attachment on the Stratos actually carries a camera tripod perfectly by sticking two legs through the loop and running the buckle around the neck of the tripod. The Stratos does, however, give up the nicely lined media pocket, the stretch-woven front pocket and Manta's included 3L HydraForm Reservoir.The stratos makes up for this by being $40 cheaper and is HydraForm Reservoir compatible offering two separate ways to hang the bladder. The first is to slide it in a sleeve in the main compartment. The drinking tube can be run over either shoulder. The second option, my favorite, is an almost hidden double zipper slot in the back of the pack that allows the hydration bladder to be hung in the space between the pack and the mesh back. I like this because it doesn't take up room in the main pack and if it ever does leak it will not wet the contents of the main compartment. Price: At the time, the Manta 25 was $139.00 and the Stratos 24 was [$] The $40 difference is more than enough to purchase a HydraForm Reservoir, but I opted to get an Osprey Raptor 10 that comes with the 3L reservoir for $54.83. So, for $15.83 more than the Manta, I ended up with a sturdier 24L pack with a reservoir option and a second Osprey 10L pack for quicker trips.Color and size: I've never measured my torso but I'm 6' with a 31" inseam – suffice to say I've got a long torso. The large (L) fits me perfectly. The magma orange is a great looking, masculine, color.

The best all day pack

I have had this backpack for 5 months now. I bought it for bicycle commuting because of the spectacular ventilation. Since then, I have climbed 9 Fourteeners in it, with hikes up to 12 hours. I have ridden in the rain with it, used it as a school backpack, traveled with it, dropped it and spilled things on it. It is 100% solid.

Pros:
-Ventilation. I don't see how a backpack maker can improve on this ventilation. The cavity created by the mesh backing is really big. It's designed to fit Osprey hydration bladders, even. I have also found it's a nice place to stow gloves, a small jacket, or even a bike lock. You will still sweat around the hip belt and shoulder straps.
-Load Carrying. I felt just fine with 4L of water, 10 essentials, food, and a jacket, for many hours at a time. No comfort problems.
-Comes with a rain cover, stored in a pocket at the bottom of the outside.
-Trekking loops hold poles for access while walking.
-The best warranty a company could give. Doesn't matter when you bought it. Doesn't matter what you did to it. Osprey will replace it. For this warranty, I automatically favor their packs when I am looking to buy.

Cons:
Straps are way too long. Osprey tried to design this backpack to fit everyone who has ever lived, it seems. Looking at the straps, it could fit someone who was seven feet tall with a 45 inch chest and 50+ inch waist. That's stupid. I (6'2", 160lbs) got the medium. I cannot see why it was neccesary to make the adjustment straps so outrageously long just so it could fit a few more people, but bother everyone else.
Water bottle pockets are slightly too small. A Nalgene bottle is a tough fit in these. Normal 24oz bike bottles fit great.
Bigger hip pockets would be nice. The current ones don't fit food bars very well. It would be nice to have pockets that could hold several Snickers bars or gloves.

Notes:
There are two places a hydration bladder can go. Either in the back ventilation area, or inside the backpack, where there is a loop and pocket to hang it. The 3L Osprey bladder is a tough fit on the outside, but possible. Overall, unless you need every single liter of space inside the pack, a Platypus bladder on the inside is much better than the Osprey bladders. The Platy bladder is much lighter.

Almost perfect

This is an amazingly comfortable little pack. It's perfect for day hikes and XC skiing. The number of pockets and the arrangement of the pockets is nice, though very close-fitting zipper covers make the operation of the zippers less than easy. I would much prefer waterproof zippers and no zipper flaps. The openings to the two smaller top pockets could also be a bit wider, and the two top compression straps partially block access into the main compartment. I simply don't use the top compression straps for this reason.

The backpack's back panel breathes incredibly well and is a joy to carry. The hip belt is similarly comfy though the small 3/4" buckle is really tiny and can be fiddly to snap closed. It carries the load well though, and overall is one of the most comfortable daypacks I have ever worn. The real head-scratcher are the thick and largely non-breathable shoulder straps though. I also have Osprey Exos and Osprey Atmos packs, and even though they are rated for much bigger loads they have FAR more breathable and minimalist shoulder straps. Very strange. I do like the small integrated shoulder strap pocket on the Stratos though, and my Garmin Oregon fits in there snugly, but otherwise well.

The two side waterbottle pockets are roomy enough for a pair of gloves or a ~24oz bottle, though a larger rear stretch pocket like on the Atmos/Exos would be very welcome too. The pack sits just high enough that reaching the bottle pockets while wearing the pack is an advanced yoga move.

If Osprey had put nice shoulder straps on this pack like on their Exos and Atmos packs, and if the zippers were of the waterproof variety (and lost the zipper flaps), plus if they had added a big stretch back pocket, this thing would be perfect. As it stands, I have to dock it one star. All that said, I would buy one again in a heartbeat. Super pack.

This is just a great little bag. If you want to do some day hiking or climbing, this bag is for you. It may not hold alot, but all the necessary things can go inside, when I take people out guiding, i can out my harness on and put a rack on my loops and that will free up space. The ice axe clip is great to clip a helmet to, just by clipping one part through the bottom lop and the other through the clip, it doesnt move around and annoy you while your on an approach. Also works as a great multipitch bag, I love the gear loop on the side, i only wish it was on the right hand side instead of the left. can fit a days worth of food water and med kit in it. The two straps on the top to cinch it togethe work great for hanging two carabiners and attaching some map case to it, like sealine. water bottle spots don't really fit your standard nalgenes or the big silo nalgenes. those gotta go inside somewhere or you carry it. This bag makes you think on your essentials and what you really need to take with you. It doesnt really allow you to carry any backcountry luxuries with you.Trekking pole holder works great and the rain cover is awesome. I love free rain covers in bags. Works great, will keep everything dry in a downpour like in Pisgah National Forest in Brevard, NC. Which is a temperate rain forest, it rains typically everyday or every other day which is where I guide in the summer. Rain protection is great. The nylon ripston material is really abrasive resistant and you can drag it over rocks and such all day long. Would not be a good caving backpack. Overall this is a great little bag from osprey.

Very versatile pack.

I recently returned from a 4-week missions trip to Senegal, West Africa. On my trip I took both a Gregory Baltoro 65 and this Osprey Stratos 24. During my stay I knew I would be taking a few multi-day trips to other parts of the country as well as many full days in Dakar, Senegal's capital.

I. love. this. pack. It quickly became a staple to my days and seemed only limited by my own inventiveness.

I would load up a 100 fl. oz. Platypus bladder daily. Navigating such a large bladder into the sleeve in the bag could be cumbersome, but with a little practice it became more manageable. The difficulty lies in the curvature of the back portion of the pack, which causes the bladder to crease in the middle.

During my stay, I was a little apprehensive to be storing $100s in both cash and equipment in a bag with only zippers to keep hands out. Here's where the inventiveness comes in. Osprey's zippers are designed as loops and you can run the pack's straps through these loops, tighten them, and have far more secured belongings.

I had to travel on a 14 hour boat ride at one point and buckled the waist strap around my chest and laid back on the mesh suspension for a great pillow. The mesh suspension also provides a PERFECT amount of space to slide in a pair of sandals and maintain easy access.

The pack is tremendously comfortable and spacious. I thought that a few of my trips would require the 65L for sure, but I was able to pack 5 days worth of clothes and necessities into this bag. Granted, it was tight-but very manageable.

Anyone looking for a great bag, search no further.

Great daypack, nothing more

This is great for what it's designed to be: a low-capacity daypack. I fell in love with the Airspeed suspension on my wife's older model Stratos 24, and the latest versions represent an improvement on what was already a key selling point for much of the Osprey line. BUT...

The older Stratos packs had more tiedown options and the oh-so-useful stretch pocket on the exterior of the pack (no raincover, though). I used that pack on the Highline Trail in Glacier NP and loved it so much I bought one for myself, albeit the newer model.

Granted, it is a daypack, but whereas the older Stratos 24 could pass for an overnighter thanks to its external organization, the new one is too streamlined and small to do so. I just learned this on the Ice Age Trail, where my son wore the old Stratos 24 with pad and camp shoes strapped to the outside while I wore the new model and struggled to fit 1-night's worth of light-to-UL gear inside. Awkwardly, I managed to strap a UL tent under the closure straps--but both the tent poles and the pack's buckles seemed to protest. I returned my Stratos for a larger capacity model. It was out of stock, so I ordered an Exos 46, which has a modified version of the same excellent suspension system, more capacity, and lots of external tiedown options. Its a bit large for a daypack, but it cinches down and is feather light.

Bottom line: if you never overnight or have the money to own multiple high-end packs, this is great. I don't, so I'll use my Gregory Whitney (90+ liters) for slogs and the Exos for everything else.

Daily commuter

After reading the reviews there isn't much else to say. It seems like some of the reviews must be on an older model because the negative aspects pointed out (cross-member disconnect, bladder difficulty) have not matched my experience.
My only down-sides are that the mesh side pockets won't hold a 1-liter nalgene. They will hold a 0.75l cycling bottle. Otherwise, the pictures indicate mesh storage pockets within the front zipper which is not the case. Would have been nice, but not necessary. The pole-stow system seems good at first, but the poles are stowed in a way that conflict with swinging your left arm naturally so that bugged me after a while.
Aside from that, I've taken this bag on several day hikes and have no complaints. Heavier items seem to go well in the bottom, otherwise the curvature in the ventilation system will put an odd weight on your hips.
My primary use for this bag, though, is my daily bike commute, 21 miles each way. For this, the bag can't be beat. The ventilation system works incredibly well, the scoop-like curvature seems to bend the wind over my back and, well... on out the bottom.
The shoulder straps vent more than I thought they would, indeed on 90+ degree days, my shoulders are the only sweat stain on my shirt when I get home which is remarkable given the amount of sweating I normally do (gross, right?).
The other comment about the rain cover needing to be secure at the top is on the mark.
Don't think I could have found a better bag.

Negative Reviews:

I bought this bag before going to Europe to study abroad, thinking I'd use it for weekend excursions. I wouldn't buy it again and am going to attempt to return it now that I'm back in the US. My main complaint is that the rigid, curved back (while cool and comfy) severely limits the size and shapes of items you can put in the bag. For example, my 15-inch laptop barely fits, even when it's just in a neoprene sleeve. With the laptop (or any other larger, rigid or semi-inflexible object, paperback books, shoes, etc.) in the bag, it is super difficult to fit anything else in there. A big disappointment to me since I blog and wanted to be able to bring my laptop with me to different places. Also disappointing is that when the bag's main compartment is full, the side mesh pockets don't stretch open far enough to fit a water-bottle of any size. In short, this bag would probably be great if you're carrying nothing but clothing. If not, I recommend looking for something else.

Comfortable Pack, Big Design Flaw

I have owned this pack for less than six months. I have hiked numerous times with it and for what it is, a lightweight backpack, it was working great. Unfortunately the frame on the pack has a design flaw. The frame has two vertical stays with a perpendicular metal cross-member that is merely wedged in between the stays and held in place by two flimsy pieces of fabric. Well, once it falls out(and it will) this pack is rendered uncomfortable as anything in the pack can and will be jabbing you in the back as you hike. Furthermore trying to get this cross-member to stay in place again once it falls out is always going to be a temporary repair.

I have owned many backpacks and this Osprey is a big disappointment. This is a

Disappointed

I have always enjoyed Osprey packs. They have great durability and utility. My Osprey briefcase has been all over the world and is still holding strong. I did extensive research before getting the Stratos24 and feature wise it seemed to fit my needs. I have had nothing but regret since getting it. The air and suspension are nice but the sleeve and routing of the bladder are horrible. It is not an easy pack to pack, bladder fit is not user friendly, if loaded anywhere near capacity things bulge and poke or are impossible to retrieve. I hope newer models are better.

I have had this pack for quite some time now. I plan on returning it for something larger.
Since Ive had time to adequately test this bag, Im going to throw down a straight-forward review for those of you considering the Stratos 24.
Make no mistakes this pack is great. It's well designed and when it comes time to perform, it does not disappoint--to a degree. The name of the game here is day hikes. Some people have written that they can fast-pack or rock a minimalist over-nighter out of this pack. Some people even claim they can go up to three days out of it. I call shenanigans. With the compression straps loosened all the way, I can fit either a fleece or soft shell, first aid kit, 2 liters of water, one day of food, my headlamp, a spare knife, a role of duct tape and a small amount of cord into the main compartment. If I'm extra careful, I can also get a water filter in there. Recently I used it for an over-nighter. I managed to fit my sleeping bag, one beer, an extra layer, my headlamp, and a small first aid kit. In the top mesh pocket, I can fit my wallet, a pen, a small moleskin, and my ipod or camera and my keys. Originally I used this pocket for sunglasses but on a short hike with a loaded pack, I reached for my glasses at the end of the day, only to find that they had somehow been smashed and irreparably damaged. Now, eye wear stays on my face when this pack is on. The other small pocket on the top is useful for miscellaneous items, but with a full pack its difficult to load or retrieve anything. The pockets on either side of the lumbar straps are very cool, and quite handy. I generally reserve the left one for trash (mine or whatever I might find along the way). The right one holds anything from snacks to gear I may need to access quickly. In addition to that, there is a pocket located on the right shoulder strap for your phone or gps. An iphone will not fit. Any small brick phone will fit wonderfully and securely, and access is easy. I really love this feature.
Another feature I particularly like is the rain cover and stash pocket for it. Located towards the bottom of the bag, above the gear loop is a small zipper. Unzip it and pull the rain cover out, and wallah! Dry bag. That being said, its not totally waterproof and pressure points will allow water to get through in heavy rain. No big deal though, unless you deal with downpours on the reg.
The gear loop on the bottom of the bag is pretty useless. An ice axe will fit well, and there is a small elastic snap mid way up the bag to secure the shaft and keep it from wriggling loose. You might also be able to carry a pack shovel with this feature, but do so at your own risk. I attempted and do not recommend it, but with the right handle, your shovel will stay put. Frankly, I would not attempt to ski or mountaineer out of this pack.
The airspeed back panel is a pretty nifty feature. On hot days it makes quite the impression. However, if you're expecting a sweat free back, you'll be sorely disappointed. The AirSpeed system makes a difference to be sure, but your back still sweats, albeit to a much lesser degree than with other packs. This system also presents somewhat of a catch-22. In designing the pack to breath, and choosing to do so with a fixed external frame, Osprey drastically limited the carrying capacity of this pack. Simply put, the frame basically makes it impossible to carry books or a laptop because of the concave shape of the frame. It is nice however, to be able to throw gear wantonly into your bag and not worry about a lumpy mass digging into your back.
The shoulder straps are comfortable and this pack features adjustments normally saved for much bigger packs. The lumbar strap system works well, though the straps are much too long for my tastes and serve only to get in the way. The chest strap works well, and the whistle in the buckle is a welcome sight. Comfort and adjustability aside, if you overload this pack (which is easy to do) you will suffer mercilessly. I've been using this as a crag pack for the six weeks now, and if Im honest, its a hellish ordeal to try and carry anything more than my draws, harness, shoes and chalk bag. I fandangled my rope onto the top of the pack via the two cinch straps located posterior to the shoulder straps, but anything more than a mile or two becomes unbearable and I have to stop and take my pack off. I recommend keeping it below 25lbs whenever possible.
Inside the main compartment is space for a three liter water bladder and dual port holes (left and right) to feed your hose out. There is no dedicated hose holder, however both straps have elastic bands which can be used to keep a hose well out of the way. There is a strap to hang your bladder located against the back panel of the pack, but accessing it is a a nightmare, and the top mesh pocket needs to be empty if you seek to stand any chance of securing your bladder. Also note that due to the shape of the frame, pack space is eaten up by a fuller bladder and its very easy to place un-due pressure against it.
Bottom line:
This pack is light and sturdy, and for anyone looking for a very solid day pack, this would be a worthy addition to your gear selection.

Pleasantly Disappointed

I was looking for a backpack that could handle it all: Long day hikes, bike rides, canoe trips, picnics, trips to the beach, or a simple night at a hotel. What I like about this pack is that it is extremely comfortable due to good suspension and plenty of air flow through the back panel (probably too much), the pockets on the hip belt are easy to use and large enough for a phone, wallet and keys. The problem is that those pockets are the only ones that I enjoy using. The large main compartment is difficult to load and unload because of the extreme arch in the back (for ventilation), it gets much worse when you use a water reservoir. The large main compartment is far wider than it is deep which has only been a problem when trying to load or unload my dSLR camera, but for extra layers or smaller objects it has not been a issue. When the main compartment is packed full the zippers seem to snag and the two smaller compartments are difficult to access because they are on the inside of the main compartment. I would never put a fragile or quick access items in these pocket because they get smashed in by the items in the main compartment. With that said I always seem to get the items I need into the pack, I have yet to leave something at home because I could not fit it into the pack. For a 24 L pack it seems to have a large capacity. This pack works great for small or flexible objects but any rigid items of decent size will cause problems.

Osprey Stratos 24

This pack seemed like it would be pretty awesome, and the comfort was, but a few things weren't so awesome. The mesh pockets could hardly fit my 16oz nalgene, and trying to get a 32oz in there was a huge challenge.

When you open the main compartment you can see that the frame bows inwards taking up pack space and limiting what you can get in there. This was intended to be my "solve every problem" pack: school, day hikes, U.L. backpacking, commuting, etc. I could fit 3 binders for school maximum and it was awkward and difficult to get them in.

As for fit, I'm 5'10'' 150lbs and the medium was too large even with my torso measuring 48cm. You really have to cinch down the shoulder straps to get this thing off your butt. I also noticed that the frame kind of pinched me a bit on the bottom.

I'd recommend that you try this one on in store just to get the proper sizing and to see if you like the loading system. I wish it worked out for me because it was super comfy.

Over this pack is very comfortable once you get use to the frame resting on your lower back. Shoulder straps are super comfy compared to gregory's z30. Air speed is good but sticks out too far, making the pack hard to pack and access issues. The mesh side pockets are pretty much useless. They are too tight to put a 16oz water bottle without a struggle, most ppl carry 32oz . I guess you can just use a bladder but then it eats up about 30% of your space. The airspeed sticks out too far IMHO and into the pack itself. Gregory's z30 leaves about an inch between support rods and pack so bladder has some more room. The extra pockets are pretty useless also once the pack is full since they rest right on the pack and have no give to them. If they stuck out a little or designed differently then it would be better. If you only half pack your pack, then this is a great pack but then I would just suggest getting a smaller pack.

Just a Tad Off

I was looking for a good backpack that would get me through my last years in college and then double as a solid daypack after graduating. I was a bit concerned that the 24L would be a bit small to fit a laptop and books inside so i opted for the large in hopes of being able to squeeze every last bit of room for the pack. i'm a little over 6' and 210 lbs and what i found is that the large is veeery long and you really have to cinch up the shoulder straps to get the pack to sit where it needs to on the hips. also because of the suspension of the bag, you can't just zip open the top of the bag and slide in books or a laptop, the cargo space of the pack is actually a slight rainbow from top to bottom. Also the side pockets do NOT fit a nalgene, which completely blew my mind. All in all a decent pack, not the greatest but better than my old jansport backpack.

Tough to get a good fit

Loved the pack. It was super comfortable and breathed like a dream. The large was the perfect size for me however I bottomed out the hipbelt. The hipbelts are not interchangeable. I took it back and exchanged for the medium but I just couldn't get it to fit right. Loved the pack but had to take it back because of this. Wish I could have kept it, just wasn't adjustable enough.
