Osprey Atmos AG 65

Based on 168 comments across 4 communities
TL;DR
Owners overwhelmingly love the Atmos AG 65 for its Anti-Gravity suspension and ventilated back panel, which make heavy loads feel lighter and keep your back cool over long, multi-day trips. It's repeatedly called one of the most comfortable, durable packs out there, backed by Osprey's warranty. The main trade-offs are its weight (around 4.5-5 lb empty) and a hip belt that loses support past roughly 40 lb.

76% of 168 verified owners recommend the Osprey Atmos AG 65.

Backpack: Osprey Atmos 65 AG, great Pack, filled that with 30kg, plus frontpack, plus rifle and fishing rod on the outside, still carried great.

that pack was heavier and had more volume than I needed - it allowed me to carry far more weight than I should have. But, it was extremely comfortable

I had the Osprey Atmos AG 65 backpack, Naturehike Cloud Up 2 tent and an REI sleeping bag - all of which were really heavy. I have since started to buy much lighter gear.

I currently own an Osprey Atmos 65 AG and it has a full-back mesh suspension and I have never sweat more in a backpack than that one (ironically) so it never gets used

I feel like I'm having some buyer regret with my Osprey Atmos AG 65. It's such a great bag, but, 4.86lb... rough.

the backpack is an Osprey Atmos AG 65. I can really recommend both of these!

I had the hip belt literally adjusted and tightened to be as small as possible and it was still too big. Now I use a pack with no hip belt.

I used an osprey atmos ag 65 on the AT and liked it, but as soon as I was finished I ordered an HMG Southwest 3400. I was happy to exchange the ventilation for a lighter pack

I use an Osprey Atmos AG 65 for overnight up to 3-4 day trips and loaded up to 30-35lbs in the Smokies. The AG system makes the weight f

the pack I use, large enough for 3 days comfortably, have not yet found a trip where I wished it was larger. Typically I can carry 30-35lbs for a couple of days and it’s stays comfortable

And the Atmos 65 AG is a great pack — but even it is heavy.

I had an Atmos AG 65. Total crap, squeaked on every step. Search squeaking Osprey backpack and you get the idea.

Reddit▲ recommend

Definitely the most comfortable pack I've owned and this is my 3rd pack I've owned. It really disturbed weight well and the same weight in my old packs feels significantly heavier despite being the exact same.

I haven't had any memorable squeaking problems under 30lb.

Osprey ATMOS AG 65 (comfortable but squeaks hopelessly with weight >=30 lbs despite all efforts to remedy)

The atmos gave me lots of chafing around the hips and was very uncomforable for looking around, partially because of the higher built of the pack (ris

I personally have the Osprey Atmos AG 65 as my multi-day trip pack. Have drug that thing everywhere from Iqaluit to Tanzania. Most recently did a long trip in Algonquin Park. Great great bag. Sturdy. Distributes weight incredibly well. Thoughtful pockets. Just superb.

I own this exact pack and it was my first pack I bought when I started backpacking regularly.

I've recently bought the Osprey Atmos AG 65 (L). I'm fairly new to hiking and plan to hopefully hike the PCT next year or the following dependent on corona (I'm from the UK) I'm starting to realise this pack is far to heavy for such a trip.. Am I right in thinking this?

Osprey packs you mentioned are way overkill - you can likely find a more comfortable and lighter full frame pack

Osprey Atmos AG 65 liter is barely large enough, for me.

Only pack that feels good and doesn't irritate that area is the Osprey Atmos AG 65. \(I've tried on well over a dozen packs and none feel like it.\)

Reddit▼ don’t recommend

The atmos is well built pack but it’s bulky and was just overkill if you’re in the “lightweight” category.
