I purchased a new Osprey Men's Stratos 36 Pack since my old was had a lot of wear and tear and the belt zippers failed. I knew about Osprey guarantee, but couldn't wait the 8 to 12 weeks to have my old pack repaired. The new Stratos 36 has a couple of nice features one of which is the large pocket in on the back of the main compartment. My old Stratos had two pockets on top that were smaller. The main compartment on the new Stratos was only top loading, so you have to dig through everything to get to the stuff on the bottom. The old one had a large zipper that completely opened the main compartment. A feature I really liked - no digging. No matter how I adjust the new Stratos I find I can't get it to fit as nice as the old. So I sent the old Stratos 36 off to Osprey ...

I received a couple of messages that they couldn't totally repair it and offers of a new pack. Since I already had a new pack I wasn't happy with, I asked they repair the old one as much as possible and return it. Today it arrive and to my surprise NOTHING was done to it.

This is my first Osprey pack. The shoulder pads and hip belt are extremely comfortable, lots of ways to customize the fit. I really like how many smaller pockets are available for putting things in. As well as, easy access to the stash pockets. The panel loading deep pocket fits what I need for day hikes.It's sturdy and nimble feeling, it vents really well, and the integrated raincover is a very nice touch that I've used frequently. It's easy to get the hydration pack in and out. I did purchase the magnetic Osprey Sternum Strap Hydration Kit, because this is a feature I like and use. I was surprised it wasn't included. Side note the kit is easy to add onto the sternum strap.

This is a great pack. The main compartment loads easily. I liked the bottom compartment and the zippered compartment on the front. They keep your gear separated, but anything you put in them reduces the available space in the main compartment. Putting a hydration sleeve in is a bit tight. There are great pockets on the hip belt, but access to them is a bit restricted when you're wearing the pack because part of them is covered by the main compartment of the pack. The hip belt and straps are all a good size - unlike some packs that had narrow straps and little padding. I ended up returning this because the lip on the bottom of the frame ended up riding up on my hips - no fault of the pack, it's simply the shape of my hips and spine.

I originally bought the Mystery Ranch Scree 32 for day hikes, overnighters and as an emergency bag in between, maybe for travel on occasion. It had amazing features like the super accessible Y-zip opening, but it was very uncomfortable. My back was hurting within minutes of wearing it because all the weight just hung against my lower back despite many adjustments in accordance with their instructions.Enter the Stratos 34. Incredibly comfortable, airy and supportive frame thanks to super breathable open-air mesh backing/straps and great adjustability. The comfort difference over the Scree 32 was night and day. I could walk for a long time with this thing loaded up on my back, which was the most important thing I was looking for in a pack.However, everything else ...

I could walk for a long time with this thing loaded up on my back, which was the most important thing I was looking for in a pack.However, everything else about the bag is just pretty good or okay. I really miss the simplicity and rapid accessibility of MR’s Y-zip. You could “rip” open up the whole bag very quickly and get to your gear. This bag is a panel loader which is very run-of-the-mill. Works pretty well but you have to undo straps in multiple places to fully unzip it. It is nowhere near as easy to access my gear as my previous bag, but still easy enough.The storage itself gets eaten up quickly by the harsh curve of the frame (which I actually love since it keeps so much of the pack off of your back) and it also pushes your hydration pack pretty deep into the interior. However, I still think there’s plenty of space for a weekend’s worth of stuff depending on your load out, especially with the straps at the bottom (which I wish more packs in this capacity range had…)The pockets themselves are just fine, I think the extra pockets at the bottom are excessive, just make it one giant pocket. I guess it’s nice to have a designated rain cover compartment but I’d rather just toss it in there. I don’t need a bunch of little compartments. But to each their own. Also I wish it had more attachment points, I wanted to secure my big Grayl bottle in the water bottle pocket and the only sensible place to attach a carabiner was to a little tab on the pocket itself. It works but I’ve seen better from other brands.Everyone complains about the front zip pocket, how it becomes “useless” when the bag is full. However I find it awesome for objects like maps, documents, face masks, things like that. I actually really like this pocket a lot.Ultimately though, I don’t think any of these gripes are deal-breakers for my intended use. This pack delivers on comfort, support and breathability which are the most important aspects of a pack if you ask me. It isn’t the best in other areas but still definitely good enough for what I’d like to use it for.Overall I’d recommend this bag for sure. No one wants a sweaty, aching back whether it’s for recreation or travel or emergencies. It’s pretty big without being too big, offers some nice extras like straps at the bottom, and while several small things could be better it’s definitely an excellent choice in this size range.
This pack was perfect for my needs as a single day trip user. I do geologic fieldwork and carry several pieces of equipment as well as some rock samples. I sometimes pack quite a bit of weight and I am using the pack all day. I was using the 24-liter version, but this 34-liter version is perfect. Much roomier but not too big. The pack is extremely comfortable with its ventilated suspension system, waist and chest straps and shoulder padded straps. Perfect. The pack is also very durable and has many side pouches for my compass, GPS unit, batteries, bug repellent devices and pens and pencils. The REI people were very helpful in helping me choose the pack.
I own a couple of outdoor packs including Montane Cobra, Osprey Rook. I was finding the Cobra was too small for adventure backpacking. And the Rook was too big. I knew my Rook was of exceptional build quality. This new Stratos 44 is the best backpack I’ve ever owned. Incredibly durable and strong, especially the stitching. Being ex British Army and a member of the Army Mountaineering Association and the British Mountaineering Council, I live in the outdoors and stitching for me is the first place I examine on any equipment. Because this is what keeps it together, and it’s also for me the mark of attention to detail and shows the company cares about the finished product. There’s nothing worse than spending a lot of money on something and after a few uses it starts ... MoreI own a couple of outdoor packs including Montane Cobra, Osprey Rook.

There’s nothing worse than spending a lot of money on something and after a few uses it starts coming apart at the stitching. The Stratos 44 is perfect for carrying all your essentials for a couple of days, I always carry enough equipment to see me through 48 hours should the need arise. I carry a sleeping bag which fits in the bottom in a proper housing so you’re not dragging everything out. Plus a goretex bivi bag in this compartment. I carry a blizzard blanket and a Brothie group Shelter for emergency. I carry a survival kit, dry montane terra trousers, a waterproof hardshell jacket, either a Rab or a Montane jacket then gloves, hats, socks, Helly Hansen lifa and gaiters make up my extremities kit, plus food, stove, gas, water… mapping, head torches, compasses, as and enough water. This is the perfect size for wild camping, hiking, backpacking. If I was doing more Alpine I’d probably go bigger, but this is a fantastic pack, stacked with features, pockets aplenty, really comfortable to wear and keep you wired out on your back. This is my Go To backpack now
I bought this as an upgrade and expansion from my Talon 11, which I love, for some longer adventures I have planned. I’m not a minimalist, ultralight hiker, but I like a bag that holds just enough. The suspension and frame of this pack keeps the load well distributed, and even over-packed with 2.5 liters of water in it, I never felt like this was heavy. The pockets are well thought out, and absolutely bombproof. Haven’t had to use the rain cover but it’s great to have on call.Only quibble is the pockets one the hip belt are a bit hard to zip close, but that’s such a minor issue it’s barely worth mentioning.As someone who’s been hiking for 30+ years, this is a really great addition to the gear roster.
I bought the Stratos 24 to replace a Manta 36 which I found too big for my. needs. However, I was surprised at how little storage there really was in the Stratos when you put a water reservoir into the its space in the main compartment. I had to push my water jacket firmly to the bottom of the compartment. There is a small zip compartment on the back of the pack, but it has very little space. I loved the frame and the back that pushes it away from. your back with a stiff but open piece of fabric. It should keep you from getting your back too warm on hot days. The waist belt was wider than the one on my manta so that was a nice feature. But the length and width of the two packs are the same. The only real difference are the number and depth of the pockets. I decided ... MoreI bought the Stratos 24 to replace a Manta 36 which I found too big for my. needs.

bought the green version, locally. It looks very nice, is very functional and i like a lot the bottom straps (not so much >40L backpacks have them). The adjustable frame and ventilation is awesome. Ofc is a bit heavier, but i like it anyway.The only thing i dont like aesthetically is the side straps. Why in the world would you put those ugly WHITE straps on the suculent green version of the backpack?!?! you really wanted to save some money or why? or the designer didnt finish the job? :D why not black, green or that mustard yellow that already is present in the backpack? White looks cheap and will get dirty fast. Black straps would be perfect. Maybe i'll try to paint them somehow haha :D
Let me start by saying I currently own 7 Osprey sacks of different sizes. I think they are the best bags out there out there and I am absolutely certain i'll buy more! I have had a Stratos previously back in 2005 which was a great bag and so I thought I'd get another one. The latest Stratos however is a bit of a let down. Yes it has all the excellent features that Osprey provide but the fit is horrific! Whether its due to my small stature (5'6" tall, 36" chest) but I could not get the bag to sit comfortably on my back. I have adjusted straps, changed back length settings but it still does not sit properly or comfortably on my back. The back length adjustment area which is hard plastic sat right against my shoulder blades which rubbed and was very uncomfortable. I ...
