The customizable pack that does it all.

The Osprey Aether 70 Backpack is the pack that does everything from gear-intensive weekend backpacking trips to ski tours and remote summit bids. Built with outstanding load-carrying comfort, the Aether 70 features the IsoForm CM hip belt that adds stiffness and padding for better performance with heavy loads without increasing the Aether's weight.


For support, the Aether is built with a LightWire frame and is equipped with a single aluminum stay to distribute weight to the cushioned IsoForm waist belt where the load of the pack can be more comfortably carried. In addition to a large top-loading design that swallows gear whole, Osprey equipped the pack with a large front panel zipper that can be used to access deeply buried layers, without having to dump your pack out on the trail. The top lid can be removed and is fitted with an adjustable waist belt, enabling the lid to double as a lightweight lumbar pack ideal for summit bids and quick day hikes from a remote base camp. Multiple straps along the front of the pack secure everything from ice axes for alpine missions to trekking poles during week-long treks.
