Osprey Atmos AG LT 65 vs Exped Ridgeline 65
Quick take: The Osprey Atmos AG LT 65 costs $4.95 less; the Osprey Atmos AG LT 65 is lighter (4.07 vs 4.67 lbs).
Which one to buy
There's only $5 between them, so the question is whether you carry more than 40 lbs. The Osprey Atmos AG LT 65 is rated to 40 lbs, and testers called it very comfortable for anything short of the heaviest loads, with its AirSpeed suspended mesh wrapping onto the hips before you tighten the belt. The Exped Ridgeline 65 is rated to 48.5 lbs on a spring-steel U-frame with a ventilated Air Flow back. For heavier food carries or winter loads, the Ridgeline has more headroom.
The Osprey is 0.6 lb lighter as sold, and its suspended mesh is still the benchmark for back ventilation. Its sizing is simple: S/M covers 17-20 in and L/XL 21-23 in, each with five fixed one-inch torso stops. Testers measured the main compartment at about 52 L despite the 65 L label, and Osprey doesn't state bear canister fit, so test-fit yours first. A rain cover is included. Its All Mighty Guarantee is among the most generous warranties available.
The Ridgeline makes up for its extra weight with flexibility. It also includes a rain cover, plus a lid that becomes a fanny pack, and it strips down to 3 lb 15 oz. A roll-top seals out weather while a front opening reaches the bottom of the bag. Torso and hipbelt length both adjust. Exped's warranty runs 5 years on materials and workmanship, shorter than Osprey's, and its US store copy mislabels the 65 L as the Ridgeline 55, though the spec block lists 65 L.
Osprey Atmos AG LT 65
For backpackers who keep loads under 40 lbs, want the best-ventilated back and Osprey's lifetime guarantee, and can plan around a smaller real volume.
Exped Ridgeline 65
For trekkers whose loads approach 48 lbs who want a roll-top with front access, a lid that doubles as a fanny pack, and a pack that strips down for lighter trips.

Pros & cons
Osprey Atmos AG LT 65
- ✓The AirSpeed suspended mesh remains the benchmark for back ventilation in a full-size trekking pack, and the LT keeps it intact.
- ✓4.07 lb (S/M) is around half a pound under the standard Atmos AG 65 for the same volume and suspension.
- ✓$320 undercuts the standard Atmos AG 65 by $50 while giving up little in carrying comfort.
- ✓Five fixed torso stops in one-inch increments are more repeatable than the sliding webbing harness on the standard Atmos.
- ✓A 500D high-tenacity base is a sensible reinforcement on a pack whose main body is a light 210D honeycomb.
- ✓Rated to 40 lb, which is high for a pack of this weight and covers most multi-day loads.
- ✓Hipbelt pockets are large enough for a phone and snacks without unclipping.
- ✓Covered by Osprey's All Mighty Guarantee, which is effectively lifetime and among the most generous in the industry.
- ✗OutdoorGearLab measured the main compartment at 52 L against the advertised 65 L, so it packs smaller than the badge implies.
- ✗The shoulder strap padding is not adjustable, unlike the hipbelt's Fit-on-the-Fly system.
- ✗Five fixed torso stops are less granular than the standard Atmos AG's continuously sliding harness.
- ✗The suspended mesh forces the load away from the back, which is less stable than a contact panel when scrambling.
- ✗No dedicated sleeping bag compartment, which the cheaper Rook 65 does have.
- ✗210D honeycomb is noticeably lighter-duty than the 420HD nylon on the Aether.
- ✗Bear-canister fit is not stated for this model, unlike the Aura AG 65 which Osprey confirms as vertical-compatible.
Exped Ridgeline 65
- ✓A stated 48.5 lb load limit, higher than most ventilated-back trekking packs.
- ✓Adjustable torso and adjustable hipbelt length in two frame sizes.
- ✓The lid comes off and doubles as a fanny pack, and the rain cover is included.
- ✓Roll-top closure with a separate front opening gives both weather resistance and access.
- ✓Modular weight: 3 lb 15 oz stripped to 4 lb 11 oz fully dressed in S/M.
- ✓1,500 mm PU coating on recycled polyester.
- ✗$325 approaches Osprey Atmos AG 65 money, and the 5-year warranty is shorter than Osprey's.
- ✗4.67 lb as sold is heavy for a pack whose main appeal is the lighter stripped configuration.
- ✗Exped's US store description for the 65 L model calls it the Ridgeline 55, a copy error; the spec block and Exped's main site both list 65 L.
- ✗The L/XL frame adds about 2 oz over the S/M at the same capacity.
Osprey Atmos AG LT 65 vs Exped Ridgeline 65: common questions
Is the Osprey Atmos AG LT 65 really 65 liters?▾
Testers measured its main compartment at 52 L, so it packs smaller than its label. Exped's US store copy calls the Ridgeline 65 a 55 in one place, but that is a copy error; its spec block lists 65 L.
Which pack carries more weight, the Atmos AG LT 65 or the Ridgeline 65?▾
Exped rates the Ridgeline to 48.5 lbs and Osprey rates the Atmos AG LT to 40 lbs. Past 40 lbs Osprey's heavier Aether is the better choice, so the Ridgeline has more headroom in this pair.
Does either pack come with a rain cover?▾
Both do. The Ridgeline also has a lid that works as a fanny pack.
