Answering the call of the ultralight revolution, Osprey unleashes the Atmos 65 for fastpacking overnights or longer.

Given the popularity of the award-winning Atmos 50, that Osprey introduced the Atmos 65 Backpack this season is no surprise. The lightweight Atmos 65, which comfortably holds more than 40 pounds of gear, is equally suited to either an overnight or a weeklong backpacking trip. Osprey gave this backpack its AirSpeed suspension, a sturdy but lightweight system with a beefy but forgiving aluminum frame as well as strong and flexible titanium struts. This pack will move with your body as you bound up the trail, scramble on rocks, and leap across streams. The breathable mesh back panel lets air circulate so you don't sweat to death underneath your pack. This pack has thicker harnesses than the Atmos 50 to accommodate a larger load. An ErgoPull hip-belt lets you disperse the load evenly over your hips so you don't get pressure points. The Atmos 65 has a sleeping bag compartment, an internal hydration sleeve, and several external pockets for gear you want to keep accessible.

Great pack

Rating:*****
I have been using this pack for overnights and multi-day backpacking trips. I have used it to carry up to 35 lbs for up to 28 miles in a day with lots of climbing and descents. I got this pack after using (and really liking) the Atmos 35 and Stratos 18, which I use on shorter trips.

First of all, if you sweat a lot, this pack is great because of the excellent Air-Core ventilation. The effective ventilation on Osprey packs contributes enormously to their high level of comfort. I am a heavy sweater who walks and climbs fast. The arc in the pack is meant to conform to the body, which it does well. While this does influence the way you pack the bag, it does not really limit what you can pack if you know what you're doing and know how to distribute the pack weight properly when loading it up (for example: there should never be a need to stuff anything between the main compartment and the ventilation mesh). I use this with a 100-ounce water reservoir. I am still able to fit a tent, bag, clothes, food, and pleanty of other stuff without lashing anything to the outside of the pack.

This pack has performed very well. Even with a 35 lb. load, it felt secure and close to my body when ascending and descending on steep, wet rock; I was especially impressed when rock-hopping some fast rivers and streams recently. I never felt the pack pulling on me or causing me to be out of balance. I am impressed how the '09 version of these packs have been engineered to put the weight closer to the body's center of gravity; the upgrades over the older models are really impressive.

When filling the pack, you can really stuff a lot into the cavernous compartment and side/front pockets. Note: the side pockets are not really for water bottles (get a water reservoir of some sort). I also like that the pack is easy to clean after use, due to the large bottom compartment.

My only complaint is that at times the pack "creaks" a little, but that might be due to the fact that it is still breaking-in a bit.

Great for Extended HIkes

Rating:*****
The suspension is great and breaths very well. The 2009 design allows you to fit much more into the main compartment than any other breathable pack I have seen (significantly better than the 2008). The 2009 also has water bottle pockets that fit bottles diagonally so you can actually reach them (I used a 1.5 liter SIGG).They are just about as light as the Exos but are made of a more durable material. I especially love the stretchy mesh drying pocket and compression straps.

I was surprised when comparing the Atmos 35, 50, and 65 because the main compartment on the 35 and 50 are almost the same size if you only pack to the top of the frame (I hate packs that stick up high). The 65 has additional space due to the zippered lower compartment.

If you intend to use the pack for travel on a plane or want the flexibility to compress it down and have a great day bag – get the Atmos 35. Even the large size can be carried on any flight (except flights out of the UK – the large size was a few inches to long if they actually measure however I was able to get mine through security b/c it looks enough like a normal back pack). Also the zippered main pocket makes accessing the main compartment and things packed at the bottom much easier.

If you know you will be hiking light, go with the 50. It has a brain and extra space above the frame if you need it. It does not have the lower pocket and will distribute the weight of lighter loads better. In addition if compressed lacking the lower pocket will make it better for a day bag.

If you are only using the pack for extended hiking and camping I would probably go with the 65 because I like the zippered lower pocket on the 65.

Roomy, versatile backpack

Rating:*****
The Osprey Atmos 65 backpack provides a great balance between form and function. Having used many backpacks over the years, this is by far the best of the bunch from my experience. My backpacking trips tend to range from 2-to-5 days in duration, and the Osprey Atmos 65 exceeded my expectations. Despite it being lightweight for a 65 litre bag, the Atmos 65 is plenty sturdy and extremely comfortable for multi-hour / multi-day hikes even when fully loaded. While Osprey claims the padding is "moldable", I have not taken advantage of this design feature. In fact, I found that I did not have the need as the pack fit me perfectly using the standard adjustment straps.

One of the more pleasant surprises of this backpack were the ample and conveniently-located storage pockets incorporated into the most easily-accessed areas of the pack. The zippers are sturdy, non-catching, and easy to reach.

As noted above, I've used this bag for several 2-to-5 day backpacking trips, and found it to be perfectly suited for that purpose. While the Atmos 65 does compress/expand easily allowing the camper/hiker to use as much (or as little) of its equipment-carrying capacity as needed, I think it it best suited for multi-day trips as compared to day trips or a single, overnighter.

As you can tell, I am a big fan of this bag. However, I do have one design improvement recommendation for the folks at Osprey; make the top-loading bag-cover / compartment detachable. This will only enhance the functionality of the bag and provide more flexibility for those of us who prefer not bringing along a smaller bag for day hikes.

All told, this is an exceptional bag and is a fantastic value.

Lightweight, versatile, comfy pack

Rating:*****

For context: I am a 5'7" female. Average size. I got this a couple of years back when it was first introduced. It was my first new pack in years, and I was amazed at the difference between my old pack and this one. Things I like about this pack: very lightweight. Great distribution of weight - my shoulders were happy for days. The ventilation area doubles as a place to put your water reservoir if you want to make more space inside the pack. The pockets on the hip belt are incredibly handy for small items (tiger balm, lip balm, tissues, whatev). The extra room at the bottom for sleeping bag was very handy. also good for storing tent parts. There are a number of access points to get at your stuff, so as long as you know how you packed your bag you can get to stuff very easily. We were up in the wilderness areas of the Adirondacks and carried bear proof containers in this bag and still had room for everything else. Things that need improving: One of the elastic straps on the outside broke my first time out. This made me sad, as it was holding in my trekking poles when I didn't need them. I made it work, but they leaned awkwardly, which made tighter areas (trees and whatnot) a little tougher. This is a minor thing, though, as the part is easily replaceable. Also, the curved structure of the pack makes for a very comfortable ride, but you have to learn to pack around it. Easy enough. Overall, I'm not sad I paid full price, and would do it again. I don't expect to need another pack for years to come.

Pack Perfection

Rating:*****

This is a truly great backpack. I'm 5'8", about 180 lbs and I use the medium, which fits perfectly. I've loaded it up to 40 lbs, and done 15 miles comfortably. I bought this to replace a much heavier Gregory Pallisade which I've had for years, because my knees aren't what they used to be, and I'm trying to cut down on the weight. I opted for the Atmos 65 because it has the sleeping bag compartment, but if that's not important to you, you can save a few ounces and go for something else.

Suspension: Super comfy Air-Speed mesh backpanel. The frame does cut slightly into the pack, but this is LIGHT YEARS ahead of last year's model. I usually choose to hang my 100 oz. camelbak inside the air space (the pack comes equipped with special clip specifically designed for this purpose, and can be used in the air space, or inside the main pack). Keeping the water in the main pack takes up space (like it would in any pack); Keeping it floating in the air space 1) means you can pack what you need without worrying about a bulky hydration bladder, and 2) keeps the weight closer to your back (easier on back and knees).All of the other features are extremely well thought out, durable, and pretty damn cool. Love the zippered waist stash spots, the backpanel access points, and I've even used the trekking pole elastic cinch on numerous rock scrambles, and once when I snapped a pole.

Bottom line: Awesome pack.

Great Pack

I have been very happy with this pack on several weekend trips. There is plenty of room for everything. A zero degree bag fits into the zippered lower portion of the pack, and can be accessed either via the outside or top compartment.

I particularly like the way the pack can be used as a day pack when venturing from a base camp location, by tightening the side straps to bring the bag and reduced day load in close to the body. The top pouch can also be tightened down closer to the pack body. This way there is no need to bring a separate day pack to carry food, extra clothes, equipment, etc.

The ventillation from the back panel keeps your back cool and comfortable. There are plenty of pockets with easy-to use zipper pulls.

The only negative is the inability to easily carry a bear canister. The two external straps on the bottiom of the bag are too short to attach the cannister without a separate carrying bag.

The equipment loops on the back are great for clipping on gear that you don't need inside the pack. Also, the 2 belt pockets are perfect for trail food and a camera.

After using external frame packs for 35 years, I am a convert to the internal frame of this Osprey.

The only pack I use!

Rating:*****

I've used this pack for a year and a half and it's done everything I've asked of it and more. First off the tech specs are wrong: the pack does have gear loops and ice axe loops, just look at the picture! There is a "shove it" pocket that could hold a shovel. I've overloaded this pack and it always had a little room for more. One liter platy bottles fit just right in the side pockets. I've wrapped a 3/4 ridgerest around a thermarest for winter camping and the back straps were long enough. I use the sleeping bag compartment to hold my two man tent. I shove my sleeping bag deep into the main pack bag. Everything else goes around the hydration sleeve. Rain gear goes outside in the right zipper pocket. Filter and mug in the left one(with room to spare in both). The top lid always has room for that one more thing. Snacks and camera in the belt pockets. I do agree that zipper work is a two handed job. When you get to camp ditch everything and this is the best working hydration pack ever!Remember this is basiclly an ulta lite "frame" pack. If you ditch your bulky, heavy gear and pack right this pack will see you anywhere.

Nice Pack!

Rating:****

As usual, as with all Osprey packs, attention to detail and construction on the Atoms 65 is excellent. For me, Fit was a little bit of a problem. I'm an "in-betweener". My waist is now all the way up to a 35 (winter was brutal on my figure!) and my torso length runs 19 to 21 depending on how I'm measured. AFter exchanging packs a couple of times, I decided the Large was my best option.
I just recently did a 3 day trip and found the pack to be good, but not great. For me, the pack became uncomfortable when loaded above 33 lbs. The belt just doesn't seem to be enough... above 33 lbs the pack transfers more weight than I like to my shoulders. The ventilated back mesh does its job; No sweaty back with this pack! I found the bag allowed better organization through the use of it's many pockets! I especially liked having the option of hanging my reservoir either directly behind the back mesh (where it takes up no pack envelope space), or in the traditional spot inside the bag. Nice Pack... might have been a 5 star pack if I wasn't an in-betweener. Note: This pack is NOT an adjustable torso length type.

A great organizer bag

Rating:*****
The tall version really fits my 6' 2" frame well, hip belts snug down securely and the belt pockets take a small a camera, sunscreen, lip balm and a half pound bag of trail mix. The option for hydration bladder inside or outside (in mesh area) works well and increases the internal volume, which is limited for rigid objects due to the curved suspension system. Don't expect to get any size bear proof container inside this bag. I used it all winter, with snowshoes, ice ax and crampons strapped to the outside and with loads up to 29lbs the bag and I traveled comfortably up 6000 foot peaks on 8 hour, 12 mile hikes. The front shovel pocket is roomy enough for wet rain gear and the top pocket ideal for gear that is needed quickly, like goggles, shell mitts and headgear. The compression straps and front pockets allow smaller loads to be carried on day trips without the bag appearing oversize for your summer day hike, and at 3lbs 12 oz its no burden to take it along. A very robust bag that shows no signs of wear and tear after squeezing past countless spruce trees bushwhacking in New Hampshire.

Best Backpack On The Market!

Rating:*****
This backpack is just about as good as it gets! Every zipper, seam, chord, material is perfectly built. The fabric is stretchy on outside parts where you put water bottles and any pocket for bulky equipment.

The hip and shoulder belts are extremely comfortable and the back panel is not only awesome to look at, but useful. The buckles are designed to be lightweight but their also tough at the same time.
The only con I can barely think of is the curvature of the frame. It's curved a lot more than I thought and it does restrict a little amount of space inside the main compartment. It's definitely not a big problem though for everything else you get. It also has many perfectly placed pockets for all types of gear and I love the huge hip belt pockets for quick items and granola bars.

Make sure to try on the 3 different sizes first so you know exactly what torso length you need to be comfortable. Overall the Atmos is close to perfection and I would definitely recommend it to anyone.

Needs some improvement

Rating:**
I tested this pack for two weeks at 11,000 ft. and as a university day pack. Mountain test: I have a 33/4 waist and wear the medium. The origin of the weight belt in conjunction with the metal hoop style botton pushed against my ever so slight love handles. This is a new, awkward sensation, so maybe I just need to get used to it. However, it felt confining. I did not like it. When the main compartment is stuffed to the max, the side water bottle pockets do not really stretch enoug and the front two pockets lose their space since the pocket fabric is so tight. The top lid access zipper is a little shorter than most packs of this size, so not as easy to get stuff in and out. The middle connecting strap between the top lid and the pack is not a quick adjust connection. It is not quickly adjustable like the two side straps. This is a hassle if you switch between full and partial loads with a quick lid removal for whatever reasons.
School and travel use: carry a laptop, bike and skate gear, books, school supplies, clothes, etc. Same issue with the main compartment squeezing out room in the fantastic external front pockets (main reason i bought this), same issue with zipper access and middle strap on top lid, same issue with wire loop frame, no daisy chain for extra stuff, etc. When the pack is partially full, there is no strap running from the top back of the pack over the top to connect to the front (like on other packs). This was a problem because I was compelled to move the top lid down and forward so that it would not hit me in the had and so that I could use it to compress the empty top portion. This did not make for well cinched load when not full. Too bad it has that curved and screen set up. Having to place the water bladder there was a hassle too. How would this pack be perfect for me? Increase material of external pockets so that they are fillable when main compartment is full. Increase size of top lid and length of zipper. Add the top cinch strap for extra stabilization. Place the weight belt origins a little wider apart cuz they hug me too much. Add small daisy chain(s). Reduce the curve. Anyway, it is still a nice pack. It just depends how you plan to use and your style. Have fun with it!

Catastrophic failure of a pack

Rating:**

Run, don't walk, away from this product. This is the most uncomfortable pack I have ever used. I'm a 5"10" man, 160 lbs, in shape, typical build. I bought a "Large," which still was way too short in the torso. Despite lots of fiddling, the pack still put enormous weight on my shoulders, and crunched me over, bent down like a troll hauling a wooden box of rocks on my back. Even with the waist belt up against my ribcage, the shoulder straps bore down hard on top of my shoulders, and threatened to snap my collarbones. The shoulder straps are not anchored at or above your shoulders (like a real pack), but back down behind your shoulder blades. Then, to make matters worse, the shoulder straps and waist belt have about as much padding as a small to medium hydration pack. Perfectly adequate if you are carrying 70 oz of water and an iPod and nothing else. But if you're doing overnight backpacking? They'll feel like unpadded 1-inch webbing. The final, fatal, crippling failure is the waist belt. It is attached to the pack in the back center of the pack, not the sides of the pack. The two waist belt halves are anchored about 4" apart, right behind your lumbar vertebrae. This creates bizarre, torturous pressure points and weight leverage. With me, it resulted in strains all the way down my thighs, hamstrings, calves, Achilles tendons, etc. Then, to top it all off, the frame digs into your hips and shoulders. This pack gave me the most painful 1-night backpack trip of my life. It was my first use of the pack, and will be my last. I would give it away for free, but there's nobody I hate that much. If you like style over function, consider this pack. It has all kinds of gimmicks, gadgets, whirlygigs, and those weatherproof nylon zippers that last for about 10 "zips." If you want to carry 10 pounds for about 3 miles, this pack might not be too much of a disaster. Otherwise, this pack is a statement on how pack-making has gone off the weird edge, selling consumers gadgetry and design "innovations", instead of functionality. If you built your own pack out of two-by-fours and heavy canvas, it would be more comfortable than this instrument of torture.

Ouch! Doesn't carry load well.

Rating:**
I purchased the pack for a thru-hike I will be doing this summer. I just took it out for a 3 day shake out trip. It packed up nice, but I couldn't fit my water bladder in the main compartment so I worked it inbetween the pack and the back mesh panel. This was a real pain as I really wanted my bladder in the inner sleave so I would have the airflow on my back. The curve of the pack really affects the amount of gear you can fit in the main compartment.
However; the main problem was how this pack distributes the weight. I could not get the pack to stop pulling back on my shoulders. After 3 days of rough Arizona mountains my shoulders felt like they were being ripped off my body. I believe this was due to the curve of the pack and the airspace between the pack and my back. The airflow idea is wonderful, but it made for a painful carry.
I have since returned the pack and purchased the Gregory Baltoro 70. The new pack carries like a dream. I have used Osprey products for years with great results, but this pack still needs some work.

uncomfortable

i got this pack as a gift and recently took it on a trip. during the hike i noticed that the titanium frame at the top of the bag was digging into the back of my shoulders. it wasn't extreme pain but a considerable problem. i have heard other complaints about this as well. osprey did good at removing the weight on this bag but all they weight they removed was in the padding...

Not what I expected

Rating:*
Used for many light hiking trips about 40-50lbs then used for a week long trip about 60-70lbs not made for the anything over 50lbs. I have used better packs in the military. This pack does not carry loads very well padding just not there.

One nice thing is access and compartments.

This pack has two very redeeming features, one serious design flaw and several small pros and cons. The strong points are that it is just over three pounds and very comfortable when fully loaded. Some of this comfort is from the air flow mesh (airspeed) against your back. This air flow area also creates a great place to store a hydration pack or rain gear. Unfortunately, the airspeed frame protrudes into the main compartment and reduces the diameter by half at the middle of the pack (from 14 to 7 inches). You need to be very creative when packing, especially if you need to fit in a bear canister. I would hate to try packing up quick in a storm. Also, if you do manage to fit all your stuff around the airspeed frame it makes the two outside pockets so flat they become unusable. Not to mention trying to get water bottles into the two outside stretch pockets. Pockets on the hip belts are a nice feature but require two hands to operate. Also, the hip belts do not hang open when you pick up the pack so it requires four hands to put the pack on your back. Several small attachment/adjustment features on the pack are clever and useful. The two things you want most in a pack is lightweight and comfort. The Atmos 65 fills this bill. I think I will keep this pack and use if for long day hikes where packing efficiently is not an issue.

Adequate but maybe not the best for my use

Rating:***

I got this for use as a summit pack and got this for the ultralight weight, although it barely fill the role. Construction is top notch as is all Osprey packs, and it will definitely last forever. Zippers have great pull loops that stay open and are easy to use with gloves. I will probably replace it with something else later as the curvy back might be great for hiking in the heat, but it just collects snow on Alpine runs. I would also point out that although it says 65 liters, it feels a lot smaller because of the curve pushing into the bag space. Makes packing more difficult. The 2009 version have changed this by having far less curve, so maybe it's better. I wouldn't plan on doing more than 3 days with this pack unless it's warm and you aren't packing many layers. Only Osprey pack I have owned that I regret at the moment. If I had it to do over I would probably buy the Osprey Variant but then again I wanted a summit pack and that didn't exist at the time. Too bad Osprey won't let me trade up.

newer features, same problems...........

Rating:***
don't look here for a better suspension than the last model of atmos packs, this "redesigned" padding isn't any better. let's face it, the "ventilated" parts don't keep you any cooler than other packs in osprey's collection. when it's hot out, you're gonna sweat. don't get me wrong though, i love the hip belt pockets, the front slash pockets and pole holders. i just don't think this pack carries 30-35# comfy at all. if you get sore on the hips using this pack, switch to an aether/ariel...you'll be glad you did.

Good, but not perfect

Rating:***

Picked this pack up last week for a weekend trip. Overall it was a good pack, but not ideal. The frame protrusion into the pack makes for a cool and sweat-free back, but makes it a little more difficult to pack gear. I was carrying around 50 pounds and I think this was just out of the comfort range of this pack, as my shoulders were feeling it by the end of the trip. Once at camp and a few pounds were shed the pack was awesome for day hikes in the area.

You either have an osprey body or you don't. I didn't. I like the pack a lot but my body didn't jive. I didn't like how you couldn't get to the waterbottle yourself. I had to ask someone to get it for me everytime I got thirsty. I didn't like the moon shaped compartment but I think the new model is much better. It is worth trying to see if you are one of the Osprey lovers.
