Osprey's stripped down, streamlined and svelte Aether Pro 70 is made for type-two adventures that span days or months; alpine climbing expeditions with remote basecamps, or boundary-pushing thru-hikes through unknown landscapes where the only trail is the one you make. WIth one zipper and strengthened hardware, this pack provides worry-free dependability. The hipbelt and harness are interchangeable, and the hipbelt can be custom molded to achieve a fit that's as perfect as this pack. No matter how far you go, the Aether Pro is backed by our All Mighty Guarantee, forever.

Stripped down, lightweight, lean and mean for moving fast and getting the job done. Built with rugged dependability to keep you moving strongly toward your objective, no matter how big.

LIGHTWEIGHT AND STREAMLINED
These packs are built for those who appreciate efficiency and create their own specific systems of organization based on their unique needs, whether expedition mountaineer or explorer of points unknown
