Pros & cons
Osprey Atmos AG 65
- ✓The AntiGravity suspended mesh is the most-praised suspension on Reddit — owners consistently say a 40 lb load feels dramatically lighter and rides on the hips rather than the shoulders.
- ✓Back ventilation is genuinely class-leading; sweaty-back complaints that plague other 65L haulers largely disappear with the full-length trampoline mesh.
- ✓The adjustable torso and Fit-on-the-Fly hipbelt let one pack fit a huge range of bodies, which is why REI staff so often point first-time buyers at it.
- ✓The current generation finally includes a raincover in the box, closing a long-standing gripe against the price tag.
- ✓Owners report the harness stays comfortable deep into 12-mile days in a way cheaper framed packs don't, especially with loads over 35 lbs.
- ✓Storage layout is excellent — dual-zip hipbelt pockets, a huge front stretch pocket, and side access to the main compartment.
- ✓Osprey's All Mighty Guarantee repairs or replaces the pack for life, and Reddit is full of stories of decade-old Ospreys fixed for free.
- ✓Resale demand is strong; used Atmos packs hold value better than almost any mainstream backpacking pack.
- ✗At 4.6 lbs it is more than double the weight of an ultralight framed pack, and r/Ultralight regulars consider it the definition of overbuilt.
- ✗The rigid AntiGravity frame makes the pack carry 'big' — it does not compress well for lighter weekend loads.
- ✗The curved mesh back panel eats into usable volume, so its 65 liters packs smaller than a Baltoro's 65.
- ✗The tensioned mesh makes it awkward to fit wide items like a horizontal bear canister low in the pack.
- ✗Price has crept to $370, and several Reddit threads note the Rook 65 delivers most of the function for a bit more than half the cost.
- ✗The hipbelt padding, though improved, still bottoms out for some users when loads push past 50 lbs.
- ✗The suspended mesh can twang and creak when scrambling or moving fast on uneven terrain.
- ✗Water bottle pockets are angled for reach but shallow, and taller bottles eject when you bend forward.
Gregory Deva 60
- ✓A 60 lb manufacturer load rating is the highest of any women's pack here, well past the Osprey Ariel or Aura.
- ✓Response A3W suspension adjusts to body movement rather than locking to one static position.
- ✓A rain cover is included at a price where Osprey's equivalent Ariel 65 does not include one.
- ✓Three frame sizes each with about three inches of adjustment covers a genuinely wide fit range.
- ✓210D over a 420D base puts the tougher recycled fabric where packs actually wear through.
- ✓Hipbelt pockets are sized for a phone rather than being token.
- ✓The 70 L sibling shares the suspension for expedition-length trips.
- ✓Gregory's lifetime warranty covers manufacturing defects for the life of the pack.
- ✗At 4.7 lb it is heavy, and reviewers note it feels overbuilt below about 20 lb of load.
- ✗$370 is top-of-market and matches the Osprey Ariel 65 exactly.
- ✗Measured main compartment is 45 L against 60 L advertised.
- ✗The auto-adjusting suspension adds moving parts that a simple frame does not have.
- ✗The 70 L size has no independently measured weight published.
- ✗Overkill for weekend trips, where a Maven 58 carries the same gear a pound lighter.
- ✗Gregory's site blocks automated access, so pricing rests on gear-media list figures.
- ✗Bear-canister fit is not stated for this model, unlike the Amber 68.
