Rated 4 out of 5 by from 2nd Osprey Pack Bought this pack about month ago. Have used on couple over night trips and day hikes. Excellent pack size for both needs. Back Mesh System is excellent especially on hot desert treks. Very easy and comfy ride. Adjusts well between hips and shoulders. Absolutely could work for 2-3 night trip if not required to carry lot of water and you have more ultra light gear. Plan on using soon on 4 day 3 night trip into Grand Canyon. This is my 2nd Osprey Pack (other Aether 60) and I am confident I can cover any planned trips. Only gave 4 stars as I wish the mesh pockets were designed to allow access to water bottle with pack on.

Rated 5 out of 5 by from It Has Pockets! Love the vertical zip pocket, side pockets, mesh pocket inside the pocketed top, the rain cover pocket, the "sleeping bag compartment," which is really just another pocket and the hip belt pockets which are not "too small" for my needs. Lots of ways to store small items without having to open the top. Also like the bottom straps! and trekking pole holder. Coming from Kelty Redwing pockets territory, I found many Osprey models to be lacking in their larger backpacks. This is a perfect backpack/daypack size and I prefer the interior sleeve for my insulated (ice!) 3L Camelbak. No noise issues...yet. After buying this pack I saw that the Mantra has the super-comfortable AG shoulder straps....but I prefer the Stratos features.

Rated 3 out of 5 by from Very Noisy! Very disappointed! Not pleased! Never had a pack that squeaks! So much for quiet hikes. Disappointed with this "upgrade." Had previous version, and very happy with that. (Car was burglarized.) Also, strap loops ripped out as soon as I put pack on for the first time! "Side pockets" for bottles are no longer accessible without removing pack. Upper strap pockets for whistles, etc. - non-existent! Front pockets for GPS - no longer large enough!! Who did this new design?? First year engineers, fresh out school??? What was a very good design, has become mediocre.

Rated 5 out of 5 by from Perfect pack for day hikes and winter activities My 20 years-old 42 litres Lafuma finally died completely and it needed a replacement as I now had a large gap in my pack stable: I have a 14 L Osprey Raptor for mountain biking and light summer hikes, then an Arc Teryx Bora 60 and 80L. I did not want to buy other dedicated packs (i.e. a light one for summer, and an alpine type pack for winter), so I wanted one that could do it all, and I had a lot of requirements: enough attachments to carry xc skis, snowshoes, and Microspikes, between 35 and 42 L to carry enough warm layers and food for day winter outings, have a ventilated mesh back for summer hikes, be very lightweight, be compatible with hydration bladders, sturdy and comfortable hip belts with large pockets for snacks and cell phone, sturdy pack material, side or bottom access (my old one was only top load and I kept having to search for everything). have a rain cover or be water resistant, have some way of attaching trekking poles... I was headed to a weekend in the Adirondaks and put all my gear in my Bora60 as I did not have a day pack. I stopped on the way to the mountains and picked the Statos and I am so glad I did: it ticked all the boxes and with all the same gear in it, it really felt like the weight dropped by 30-50% (to be fair the bora 60 is a heavier pack)! The trekking pole stow and go is really handy and works well. There are a bunch of small details that are great about this pack - key clip holders inside the top part are easy to use, there are holes in the side pockets to have the compression straps run inside or outside of the pocket. IMPROVEMENTS: It would be nice if the pack came with a magnet to attach the hose from an Osprey hydration bladder. I have only used the pack for 3 days and I can see that everything white will be an ugly and dirty brownish color in a few years; grey would have been more practical. I would have liked the bottom compression straps to clip instead of being inserts.

Rated 5 out of 5 by from Oh what is this perfect little thing? I've never been more excited. It is like this new bag was custom built for my happiness. Can't wait to see just how perfect it really is.

Rated 4 out of 5 by from First Osprey pack - impressed but not blown away This is my first Osprey brand pack. For my torso size, this model was easily the most comfortable of the bunch when compared to similar capacity models. Impressed with how some of the features were thought out, but not all of them. PROS: Side entrace and top loading features are nice for easy access. Adjustable shoulder system works well. Airframe suspension keeps my back dry. Warranty. CONS: Bottom zippered compartment is separated from main cargo area - nice for separating gear, bad because it decreases space in main cargo area. Wish they would get rid of the rain poncho - wasted space and added weight. #1 major problem is that when inserting the drink tube from a water reservoir through the slot it was designed to work with, the tube "squeaks" loudly. This is due to how the material tightly overlaps. Makes it useless, I have to route mine through the side zipper so I don't go nuts from the sound. Overall I'm happy with the pack for the features and price. Not happy they moved manufacturing outside the US but that's how the world works now, right?

Rated 5 out of 5 by from Very nice pack I had to return it because I underestimated how much volume I really need. It is an excellent pack though, thoughtfully designed.

Rated 3 out of 5 by from Lightweight maybe a lil undersized Good pack. Slightly undersized for multiple day hikes.

Is the divider for the sleeping bag compartment non-removable like the previous edition of this pack? or can I remove the divider and access the main compartment from the sleeping bag compartment. 

Asked by: Kyle2212
​The divider in the sleeping bag compartment is not removable.
