Employing Osprey's Airspeed Suspension the pack’s tensioned mesh back panel provides flexible support and breathability to combat heat build-up between your back and the pack body.

Accommodating hikers of varying size the Stratos 36 is available in Small/Medium (fits torso lengths ranging from 16”-20”) and Medium/Large (19”-23”) size options. Adjustability in the harness load-lifter straps and sternum strap enhance fit.

The storage capacity of the Small/Medium pack is 2014 cubic inches and the Medium/Large has a 2197 cubic inch capacity. In addition to its traditional top access point the main packbag can be reached through a zippered side panel entry. Additionally a lower compartment serves as a dedicated spot for stowing your sleeping bag or other clothes and gear. A front zippered stash pocket two side stretch pockets and dual pockets on the pack’s fixed lid offer additional organizational options.

Other features include a Stow-on-the-Go trekking pole attachment removable sleeping pad straps an ice axe attachment with a stowable bungee tie-off and an integrated rain cover.

Great pack for the money
Reviewed by Dexter K. - September 24, 2018

Likes: Surprising amount of space can handle a weekend trip if packing light. Very comfortable and included rain cover is an awesome bonus.

Dislikes: Straps move around when loaded down

Excellent backpack
Reviewed by Danimal - September 24, 2018

Likes: Great for both day hikes and 1-2 nights. Very adjustable for a good custom fit.

Dislikes: None.

Updated model
Reviewed by Benjamin T. - July 17, 2018

Likes: I had the previous Stratos 36 and decided to check the new one out and see the updates. The suspension is improved noticeably. It's not an AG suspension but is "AG inspired" in that it uses a single piece of mesh for the back panel and interior of the hipbelt. The new model also adds a convenient exterior pocket. If you're looking for an overnight/weekend version of an Atmos, this is the closest thing to it. Go with the 36l version over the 34 for the top-loading and you won't regret it.

Dislikes: A little heavy for a 36l pack.

Great Pack for Day Hikes and Short Camping Trips

Dislikes: None yet

Good pack for a weekend trip
Reviewed by Russell K. - April 8, 2018

Likes: This pack comes with an attached rain cover in its own compartment, easy to put on and put away. Its description is accurate, it's a smaller pack for backpacking trips but is enough to hold the essentials.

Dislikes: The top of the pack has a bit odd of a drawstring which makes it a little difficult to open and put in or take out gear. The height seems fine to me, but a taller person may not necessarily like the placement of the waist and chest straps- but I am not one to speak on account of them.

Great backpack for day use
Reviewed by Tejas S. - April 7, 2018

Likes: Looks like it is well made, has quality material, feels great on my back and enough room for all my stuff plus kids for day hikes.

Dislikes: None yet but I've only taken it out once. I'll update once I have more miles with it.

Super comfortable day pack!
Reviewed by James H. - July 20, 2017

Likes: •Feels like a custom fit - super comfortable!
•Generous hip belt for big guys
•Easy access to pole loops, water bottle pockets and packed items (through side zipper)
•Room for a 3L hydration bladder
•Comfort, comfort, comfort!!! Can't stress this enough. The only bag that even came close in my sampling was the Marmot Graviton 38 but the comfort and ease of use of the Osprey bag sealed the deal for me.

Dislikes: •This is my first hiking bag, so I'm still learning what all the straps and pockets are for. It seems much at first, but a little searching on YouTube and talking to some hikers is quickly clearing the air about the purpose of all these items.

Suspension system!!
Reviewed by Andrew T. - June 16, 2017

Likes: The suspension system and the back panel are the best thing about this pack. When using my back stayed cool and it was great.

Dislikes: None

Reviewed by David B. - June 12, 2017

Likes: Osprey is so good at making a comfortable backpack, and they surely delivered that on the Stratos 36. I bought the black model, and it looks so amazingly awesome. I love that it comes with a rain jacket, because those things are so ridicously expensive. I love the third entry point on the side, but I've noticed after using it a few times that I haven't had use for it at all. Maybe I would if I had the 50 liter version of the Stratos instead. But seriously, the suspension system on this thing is so amazing for a 36 liter pack. I love it!

Dislikes: These two issues are the only reasons why this pack didn't get five stars from me. First, the sleeping bag compartment must be designed to carry a REALLY small bag to fit inside. I tried so hard to get my Nemo Rythym 40 degree bag in there, but it wasn't happening. One might need something that can compress into an 8x10 size to get it in there. It would have been nice if Osprey didn't seal in this compartment and have the ability to remove the shelf like what you would see in the Atmos and Aether to accommodate a larger bag.

The second thing I am not too thrilled with is the front pocket. It's just a little awkward for me to get things in and out of it. But I knew it had this design when I ordered it, so I don't want to complain too much about that.
