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.
