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.

Great Osprey Pack
Reviewed by Brian N. - June 1, 2017

Likes: This Osprey backpack has everything I need. I've used it for long day hikes and overnight backpacking trips. Waiting to use it for winter hikes to accommodate my snowshoes.

Dislikes: None.

Really Happy
Reviewed by Will G. - March 31, 2017

Likes: Just spent 2 weeks with the pack in Egypt and Israel. I love the quality of the pack. Very thoughtful design which results in easy to reach and use zippers and straps. I think that it is great as a travel bag with plenty of storage for the day trips I was taking.

Dislikes: It might be too big for some as day hike bag. I have a bunch of children so family hikes mean I end up carrying more gear.
