Why We Like The Aether 55L Backpack

Osprey designed the new Aether Backpacks with a brand-new fitting system—Osprey's best—and the Aether 55 Backpack is perfectly sized for weekenders and overnighters. The back torso adjusts vertically to customize the fit for all sizes, and On-the-Fly shoulder strap and waist belt adjustments ensure quick-and-easy micro-adjustments that you can cinch on the trail. Osprey not only integrated a rain cover, but also treated the main fabric in DWR in case you don't get the cover on in time. A LightWire frame offers surprisingly stiff rigidity when you're carrying heavy loads, and Airscape mesh provides breathable ventilation on your back.

Updated Osprey Fan Favorite

The Aether has been a flagship pack in the Osprey line for years and has now been updated. This latest version will have an easy to adjust fit-on-the-fly harness and hipbelt, injection molded back panel providing additional support, and now includes an integrated rain cover. This is the ideal overnight pack and is also constructed with bluesign approved fabrics! -Dan, Osprey Rep
