Comfortable 65L Backpack

Once fitted to your body, the Osprey Atmos 65L backpack is a great pack for a 4-6 day backpacking trip. Comfortable waste belt straps and shoulder straps, great stiff back support, main compartment fits a lot, many zippers (access points) to top and bottom of pack, lots of spots on the outside of the pack to hang equipment. Very functional and reliable pack.

Great for backpacking and shoulder season!

This is one of my go to packs for long day trips during shoulder season and backpacking trips. It’s very comfortable and has great ventilation. The side pockets make it convenient to get to smaller items on the trail. I’ve used this pack for a few years and would definitely recommend this to anyone looking for a larger pack or an upgrade.


This pack has all the pockets youd ever need. A little heavy for my liking, but treated me well on many backpacking trips.

Men’s cinnabar 65

I’m a woman who purchased the men’s backpack. The shoulder width near the neck on the female version was too close for me. I’ve loved every aspect of this pack so far. I’ve been on tons of adventures with it and after some adjustments, fits nice n comfy. Plenty of room for sleeping bag, Mat, tent, Hammock, Bear canister food stove etc. lots of pockets and stuff to stash stuff 👌🏼👌🏼

Solid pack

Probably the most common pack I see on the trail and there is good reason. Plenty of pockets for organizing, has a "brain" that can be removed, solid suspension system that is adjustable, and isn't terribly heavy.

The things I wasn't a fan of - and why I upgraded - not waterproof, easy to overpack, hip pockets are hard to access when they are packed, and I kept finding small holes around the top and bottom of the pack.

I recommend this one to start with if you are going on long trips with few camp migrations. If you are going on a thru hike, or trying to cover serious ground, you don't need 65L.

Great comfort

The anti-gravity suspension system on the Osprey Atoms AG 65 backpack sets it apart from all the other backpacking packs out there. GREAT COMFORT!
