It fits, I sits
Got this bag based on the overall ratings and it does not dissappoint. Pockets for days. You can literally fit your extended family in this and have room for snacks. Admittedly, I have not spent much time aside from getting this thing sized but hope to do some overnights and weekend trips when the sun is plentiful and the air doesn't hurt my face.

Best Backpack...
This is the most perfect backpack I could find!! I love the antigravity (AG) system, the endless pockets available, different compartments, and ample storage space. I already organized a winter hike to test it out and it was fantastic. People had same size bags, but they felt heavier, even though they weighed 3-4 lbs less...lol It's nice having a backpack I can fill without cramming stuff inside, it was so comfortable. I can't wait for summer to test it out.

Atmos AG 65 Pack
This pack is full of adjustments to suit the user. I particularly liked the hip belt adjustments which pull out the padding to help rest on your hips, not like other packs that just allow you you lengthened the strap to fit around your waist. The anti-gravity system seems to move the weigh around your back as well ( although in all fairness this is an initial quality review. Not a long term year). I did load up the pack and test this system out and liked how it shifted the load. Lots of accessible pockets. Well constructed true to Osprey brand

Good quality
Very well-made material . Lots of compartments. Wish it had a rain cover.

Atmos AG 65L Backpack
Tremendous piece of gear. I have not used it yet for hiking but tested it with its top off to carry various loads around the city. It has a sophisticated adjustment system which makes it individually adaptable and its weight support technology is great. Still learning about all of its features but I only expect to be pleased further. It should be an ideal backpack for serious hiking adventures.

Great and advance pack, but slightly heavier than expected
I brought this as an upgrade of my Gregory Stout 65.The anti-gravity suspense system gives me a much tighter hugging to my back than Gregory's VersaFit system. When walking I can tell it is less flex too. However, that takes me a while to adjust to the feel of it.
Atmos side pockets allow access from its front is very convenient to reach the contents (my old model of Stout doesn’t have that feature). Initial torso adjustment of Atmos is painful and took me 15-20 minutes fiddling around to understand how it operate, but once you get that, it is ok easy. Don’t know why Osprey doesn’t provide brief instruction with the pack that can save some frustration from user. Fortunately, this adjustment is only need for initial fitting. As said in the title, Atmos AG is much heavy (litter more than 1 lb compare to Stout 65). You feel even greater weight different when holding both empty packs side by side. I guess it is due to its rigid structure and padding. However, due to it fits better to my back actually that counter-off this disadvantage. Initial trial with full 40 lbs load on a 10K trail, I don’t feel being bog down by that extra lb. Last complain, Atmos doesn’t come with the rain cover; most other major name brands have integrated one.
Weight, ease of torso adjustment and lack of rain cover cause I drop a star in rating.
