At 1.7kg, you won't find a more supportive pack for the weight than the Osprey 70L Aether Pro. The simple, stripped down, durable design of the Aether Pro makes this a fantastic lightweight men's hiking pack as well as a climbing pack or mountaineering pack.

Osprey's streamlined and slimmed 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 at any Paddy Pallin location to achieve a fit that's as perfect as this pack.
