Why We Like The Osprey Atmos AG LT 65L Pack
Built for expeditions where ounces matter, the Atmos AG LT 65L Pack forgoes the bells and whistles for a streamlined and weight-efficient carry. The AntiGravity suspension system provides comfortable support, while external pockets and a side panel zip opening to the main compartment allow quick and easy access to our gear.

Zion Narrows- great pack
- Familiarity:
- I've put it through the wringer
- Size Bought:
- l/xl
Used the pack for couple days in the Zion Narrows. It was perfect. Very comfortable, enough room all the gear and keeps your back nice and cool. Pack is water resistant to splashes and brief exposure to water, but not water proof. I am 6"3 and 230 lbs, and the frame was big enough. The light weight is a bonus.

Very excited to use the
[This review was collected as part of a promotion.] Very excited to use the Atmos AG LT 65 on the JMT this summer! Pack Fits well I am 5'9" with a 19 inch torso and the SM/M is a perfect fit for me. BearVault 500 fits horizontal inside the main pocket and there is more than enough room for a months worth of gear for the trail! Thank you OSPREY!!

I took it on a
I took it on a trip to Texas as a checked bag. It's a lot comfier than what I used to use in the Marine Corps! I'm also using it for my 40x40x24x40x40 in celebration of my fortieth year of life. 40 lbs for 40 miles in 24 hours every day for forty days repeated every forty days. (I just turned forty. đ) I donât recommend loading anything heavier than 40 lbs in it unless you want to feel the weight. Iâll update, accordingly. Shalom and Lechaim!

uncomfortable hip strap

Hip Strap cuts into my hips, and they are not very adjustable, and non-removable. not as good of a bag as other osprey packs Ive had in the past.

Same Atmos fit with less weight
I originally had the Atmos 65 AG a few years ago and changed it out for the Exos 58 when Osprey offered the LT. The torso adjustment is the same as the Exos which works fine. The hip belt adjustment has changed which again works for me. Access to the bottom of the pack t to though a zipper has been eliminated but I never used that anyway. With the weight coming in at just over 4 pounds in nice especially know I have the comfort of the Atmos on my back.
