Stripped-down, ultra-durable version of Osprey's classic backpacking pack

Osprey's stripped down, streamlined and svelte Aether Pro 70 is made for 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. NanoFly™ fabric integrates ultra-high-molecular-weight polyethylene (UHMWPE) ripstop and 210D Nylon, creating an incredibly light fabric with remarkable abrasion resistance. 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 Osprey's All Mighty Guarantee, forever.
