Combining its hard-earned reputation as a rugged load-hauling option for extended backpacking trips with the revolutionary Anti-Gravity suspension the Osprey Aether AG 70 offers a dynamic responsive fit 4000+ cubic inches of storage capacity and a weight-carrying capacity of up to 60 pounds!

Osprey's innovative Anti-Gravity suspension system equips the pack with weight-carrying efficiency breathability and a contoured fit. A broad-mesh tensioned backpanel stretches all the way out across the lumbar portion of the pack. Though the pack maintains constant responsive contact with the wearer warm air can escape freely because of the separation caused between the mesh and the pack itself. Beneath the mesh a peripheral LightWire aluminum frame. A sliding sternum strap and adjustable load-lifter straps further enhance fit.

Accommodating backpackers of different heights the pack is available in your choice of sizes. The Small size fits torsos ranging from 16”-19” the Medium fits from 18”-21” the Large fits from 20”-23” and the Xlarge accommodates torso lengths ranging from 22”-25”. An Anti-Gravity IsoForm harness and a fully-padded moldable IsoForm hipbelt maximize performance fit and comfort. These components are interchangeable. NOTE: The Aether AG 70 ships standard with component sizes that match the torso size or “style” of the pack with the exception of the Xlarge which comes standard with Large components. If you require customization of components please leave detailed instructions about what size hipbelt and/or harness you need in the “Order Comment” field on the “Order Review” screen at checkout or call us at 1.800.617.0643 to place your customized order directly with one of our Gear Specialists.

The pack’s large main compartment is reached through a traditional top-loading access point but a large J-shaped zipper on the front of the pack also allows quick access to the interior. Additionally a lower compartment serves as a dedicated spot for stowing your sleeping bag or other clothes and gear. A removable divider enables you to open up the interior to create a single spacious compartment. A large front pocket utilizes welded stretch woven fabric to serve as a convenient storage spot for discarded layers or other gear. Elastic side pockets are ideal for stashing water bottles or other smaller items. Integrated hipbelt pockets provide a spot to keep essentials close at hand. Side compression straps enable you to cinch down your pack to keep contents safely and securely in place and also double as lash points for additional gear. Buckled straps that pass over the front of the packbag are designed to further enhance the compressibility of the pack and provide yet another place to lash gear. A removable top lid protects the contents of the pack and can be removed entirely to save weight . Adding increased versatility the lid also serves as a streamlined stand-alone daypack with its own minimalist shoulder straps an adjustable sternum strap and an internal hydration sleeve.

Other features include integrated Stow-on-the-Go trekking pole loops ice axe loops with bungee tie-offs removable sleeping pad straps and an internal sleeve that makes the pack hydration compatible (hydration system sold separately).

AG is real
Reviewed by ny4ny - October 13, 2018

Likes: AG or anti gravity is not just a gimmick. The weight does seem to disappear. It's quite magical actually. The detachable daypack is a great feature.

Dislikes: There could've been more pockets to put smaller items

Great backpack!
Reviewed by Ronald B. - October 11, 2018

Likes: I like how the hip belt takes the load off lower back. Nice option to remove top cover off and use as day pack. Recently use in Sequoia, very comfortable when loaded with gear! Very smart design and functional backpack. Highly recommend.

Dislikes: None

Great pack for carrying heavy weight
Reviewed by akibear - September 23, 2018

Likes: I used Aether 60 for a 5 day trip and a 3 day trip, it carried weights very well. Also the day pack was very functional, comfortable and big enough for essentials for a short day hike. I switched to Aether 70 for its extra 10L and the better compression system and J-opening with only a very slight weight increase.

Dislikes: As everybody else says, it is a bit on heavy side which will be insignificant when carrying over 40lb. The stiff hip belt tends to get in the way when putting on the pack since its tension wants to stay closed. Just open the belt and put your hip in first before lifting the pack.

Took it to PNW

Very Comfortable
Reviewed by Chris Z. - July 6, 2018

Likes: Very comfortable and roomy. Easy access to anywhere in the pack and a great, useable, daypack converted from the lid. Really liked using it.

Dislikes: None really...still breaking it in.

Great pack overall!
Reviewed by Nik - June 24, 2018

Likes: Very comfortable, I'm assuming even more so once I have it adjusted properly. Plenty of room. Love how the top transforms into legit day pack. The 'J' zipper access to main compartment is prime!

Dislikes: Wish there were more external pockets. My old pack had four external pockets that were very useful! I don't like how the two side pockets are not fully enclosed.
