A Great Osprey Pack

First, Osprey makes a great pack and they really walk the walk when it comes to replacement parts for life. I've had my Stratos 36 for about a year now and have put it through it's paces. You can run this pack through any type of situation and it's going to handle it. The only wear and tear has been on a couple of snap buckles and both of those where my fault and Osprey replaced them immediately with no questions asked.

I'm not sure if the air-speed suspension is all it's cracked up to be. Personally, I don't care about a sweaty back which is a good thing because I sweat just as much with this. For me a pack is all about comfort and function and the Stratos has both. There are more than enough suspension straps to lock the load in place, the pull ring zippers are really smart, the shoulder straps are nicely padded and I love the less padded hip belts. Plenty of side pockets and separators, the rain cover is a nice touch as are the small side pockets belt in to the hip belt itself. It even has a whistle! And although I don't use it, there seems to be ample room for a bladder. BUT...there are a couple of drawbacks.

First, there are no sleeping pad/bag straps. The capacity is easily large enough for an overnighter so not having straps is a big drawback for me. I've rigged mine but i think this is something that Osprey should have done considering the capacity.

Also, I've noticed that my frame will squeak...which drives me nuts. I've learned that lighter clothing positioned on the top and to the side can alleviate some of this when the suspension straps are pulled really tight. But it's something I'd prefer not to have to do. Osprey suggested silicone spray but given the position of the frame it's really hard to get to. This could just be an issue with my pack however so you might want to look around to see if that complaint shows up anywhere else.

While this is definitely bigger than a standard day pack I like the option of having the extra space...particularly during winter hikes in the snowy SoCal mountains.

This pack was a gift which is a pretty gutsy thing to give a hiker. We are all pretty particular about packs, boots, etc. At least I am. But I love my Stratos (at least when she's quiet) and would definitely recommend this, or any Osprey pack to someone seeking quality, function and stylish comfort.

This pack was my first foray into the world of Osprey and I have to say that I love what I have seen so far, for the most part. The Airspeed suspension is great. I always had a problem with putting a pack on a cold, sweaty back after a break. No longer is this an issue. My back stays completely dry. The hip-belt pockets are indeed handy, as is the pocket on the shoulder strap. Having the option of a top loader and a front loader is convenient. I don't use trekking poles, so I cannot speak on the effectiveness of the "Stow-and-Go" feature (I tried to use it to hold my Rogue Hoe, with no success).
With that said, I have three big issues with this pack and one rather minor one. Here they are:
1.) You cannot cinch down tight on the compression straps. This causes the frame to bend and the suspension to press against the pack.
2.) The design of the cross-member for the frame causes the bladder to take up even more space than it would already. The Hydroform bladders from Osprey will not fit comfortably mounted on the outside as designed.
3.) If you actually pack the main compartment then the front pocket is useless. If you do accidentally do put say a notebook in there before you pack the main compartment, you have to fight to get it out.
4.) Minor Issue - When the pack is packed, it is difficult to access the built in rain cover. Not really a huge issue, but a lapse in design just the same.
Overall, would I buy this pack again? Yes, if only for the suspension. The other issues are dealt with by simply being careful when packing. However these issues have made me realize that I HAVE to get another pack, which I was hoping not to have to do. I will stay with the Osprey line, looking at the Kestrel and the Atmos.

If I was sent off to a desert island and given my choice of one brand of backpack I would choose Osprey hands down. In my opinion they're the best. Super quality and a great marriage of light weight and function. I had the Stratos 36 for quite a few years but had a bit of a love-hate relationship with it. The love came from the functionality. The hate came from an intermittent but persistent 'squeak' from the frame. I tried lubricants but nothing worked for long. If I packed it just right I would be okay but as one who is very sensitive to noise, particularly on the trail, it would drive me nuts. One thing Osprey does offer is a lifetime warranty on their products. I had to order parts a couple of times and they got to me quickly with no questions asked. That said, the material on my Stratos started fraying around the bottom of the frame. This wasn't from standing the pack on end because you can't do that with this design. Thankfully, the retailer I purchased it from allowed an exchange three years after the purchase. I went with the Osprey Kestrel 38. More than anything it was because of the mesh back panel which is supposed to keep you cool. Personally, I didn't like it because I prefer to feel the load against my back. Some people really like the separation of the load to their body so it's a personal choice. Overall I'd say that Stratos 36 is a good choice for the day hiker who wants the capacity to carry extra gear. I especially loved it for the winter snow hikes in the San Gabriel mountains outside of L.A. Light overnights are a possibility too although the Stratos does not come with pad straps. But again, you won't go wrong with an Osprey.

The ultralight backpacker community would scoff at using even a light pack such as this, but for me it's perfect. I use the large size. I bought this originally for a larger day pack for those longer day excursions where you want to be prepared. I absolutely fell in love with the fit and features. A MT forest service ranger said it best when describing her Osprey pack: It hugs my back like a baby Koala. The Airspeed system is heaven sent for a sweat hog like me. Simple and straightforward pockets and features.
I've used other larger Osprey packs for my extended backpacking trips in the past and loved them, but I decided it was time to go lighter...much lighter. A smaller pack is the best place to start: forces you to pack lighter, more compact and saves weight right off the bat. I took this pack for 6 days in the Absaroka-Beartooth mountains. My starting total weight was 31 lbs (with water/food) and came home at just over 20 lbs (no water/little food).
This pack is a dream. For me, it splits the difference between featureless ultralight packs and the huge load monsters you see everywhere on the trails. My whole paradigm of backpacking has been changed and I may be selling off some "load monster" packs soon, The attached photo is all the gear I fit in the pack for a 6 day trip. Yes, I fit the large bear vault in there. It's the first time my pack has actually looked like the stock photos...all puffed out and perfectly full. Without the bear keg, I bet I could do 2 weeks or more out of this thing.

I'm impressed with the Osprey Stratos 36; it's the first I had heard of the pack, as my oldest son wanted a new pack for his birthday and this was on his list of likely candidates. I've had some experience with several other brands (I learned the "get what you pay for" lesson long ago) and I was intrigued with the Osprey as I read about it. We don't have a lot of shops to find packs in around my area - usually look at backpacking equipment when we do a trip to the zoo, etc. The build quality on this pack is VERY good. I was thoroughly impressed with the lightness of the pack as well, and the arched webbing that keeps the pack off the back is a great feature - no more soaking wet shirts on a cold hike! We figure that he could easily do a two or three day hike with the pack, going mostly minimal on other things; just a ground sheet and a plastic sheet for cover, for instance, but with the ability to carry enough of everything else. I like that it also has a cover sheet, which is extremely useful in the rain, at the Olympics, that's almost a guarantee! Zippers are good quality and the warranty on the pack, if to be believed, makes it good for a lifetime of hiking use. Now the only problem is how to get it off his back so that I can use it.

This is the first Osprey pack I've ever purchased, and I did so because of rave reviews from friends and internet users alike, so I figured I would post my own review. I'm 6'2", 170 pounds, and I got the large (2,319 ci), which suits my body perfectly. As other reviewers have noted, the Airspeed system allows your back to breathe, no matter the conditions. This pack is great for 1-3 nights, though I'd use a larger pack if I was hiking/trekking for a longer period of time. The hip-belt pockets are easily accessible and great for a digital camera or energy bar, and I like the front-loading feature, in my opinion a must have. However, if you're searching for a day-to-day pack, then this probably isn't the one for you. It's a bit bulky for daily use, especially if you're on a crowded bus or train, or if you're commuting on a bike. I spent 3 years abroad, living out of a backpack while teaching in Latin America and Asia, so I tend to put my packs through one torture test after another. I'm planning another long-term excursion to Australia and Southeast Asia, and this pack is definitely coming with me since it has a built-in raincover that's great for the rainy season. Once again, I highly recommend this pack for hiking, camping, and outdoor use, not so much for day-to-day city use.

Took the stratos 36 to Peru for a 5 day hike through the Andes then to Tanzania to climb Kilimanjaro. I'm 6" tall with a fairly normal torso length, and the medium fits me perfectly. Osprey nailed it with this pack. Very durable, very comfortable. Built in rain cover is perfect, and well placed. Also like the walking pole positioning on the shoulder strap, makes it very easy to put poles away when they're not needed. The ONLY drawback I've found with this pack after plenty of travel around the world in the last six months, is that it doesn't sit upright due to the 'airspeed' back. The back is curved to allow for air to flow off your back, which is very helpful in the heat - the trouble is, when you put the pack on the ground it will fall forward because of the design, so if you need to get something out of you have to prop it up while digging around. Still, this pack is amazing, and EASILY worth five stars - great value, great pack.

Mikey at Backcountry.com on 08/26/2012

I've used this twice so far and I've been very happy. I like to bring too much stuff with me, and so far the 36L is a great day hiking size for me. Holds my water, snacks, layers, headlamp, stuff for dog, and lots more, with no problem. I haven't even filled it up completely yet!
It also carries very comfortable, and the different pockets are very useful. I really wanted something that had a stretchy pocket on the back for shedding layers, which this does not. But it has a decent sized zippered pocket on the back for small items and accessories, and it also has access to the main compartment from the back. One quick zip, and I'm in the main compartment to get rid of my jacket or quickly grab it out for a sudden storm, without having to unbuckle the lid and go in through the top. So I've been satisfied with not having the stretchy rear pocket.

James Pramick at Backcountry.com on 06/30/2013

I've been looking for a couple of years for a good pack to use while canyoneering, and you'd be surprised how hard it is to find one. After lots of looking I finally decided on this one and it's been a great choice.
Plenty of room in the pack to carry a rope, harness, webbing, food (as long as you don't mind some smooshed sandwhiches) and some extra shoes for the hike in. I went with the Stratos because of the front loading feature which makes it easy to stuff the rope in the pack when you're on the move.
My only beef with the pack is that it does only have the two main pockets and the smaller of the two is pretty tiny especially if you've got the main pocket loaded up with gear. I think I might look into installing a shelf just above the front loading pocket to keep my rope separate from all my other junk.

zak harris at Backcountry.com on 05/01/2012

I just got back from a 6 week geologic mapping project in Colorado. I used this pack most every day in the field to carry all of my gear and equipment. With temperatures getting up to 110 the mesh back kept me cool. The pack was very comfortable and made my 8 hour hikes up and down large outcrops a breeze. This pack had more than enough room for everything I needed without feeling too bulky. The two pouches in front made great compartments for snacks, my brunton, and tweezers to yank cacti out of my hands and legs. If you're looking for a good day pack to carry a little more than just your lunch, the Stratos 36 is the way to go.

Neutral Reviews:

not a bad pack. does not hug your back as well as my other larger pack. construction quality is not the greatest i have seen either. ice axe stow placement is a bit clumsy given the shape of the pack.
used on the AV1 and the haute route.
