Osprey Aether 85 Pack Video

Slip the generously proportioned Osprey Aether 85 pack onto your back and enjoy the comfort of a custom, heat-moldable hipbelt and a superb, lightweight design for your extended wilderness adventures.


  • Removable hipbelt can be custom molded for a perfect anatomical fit; it offers superior load support, stiffness and padding with dual-density foam for enhanced comfort
  • Osprey-certified custom molding available in most stores—check your local REI store for availability
  • Dual-density foam harness with spacer mesh promotes airflow and wicks away moisture during warm weather and intense activity
  • Suspension features a peripheral frame, a smooth, spacer-mesh back panel, single stay and an internal framesheet
  • Running down the sidewalls, the peripheral frame anchors to the load-lifter straps and hipbelt, transferring the load to your hips and resisting sag
  • HDPE framesheet and a center aluminum stay protect your back from bulky or pointy items and support heavy loads
  • Top lid can be removed and converted into a lumbar pack; hipbelt can be removed from the pack and attached to the lumbar pack for comfortable carrying
  • J-zipper panel access on the front of the pack body makes stowing and accessing your gear a breeze, even when it's buried deep in the pack
  • Externally accessible bottom compartment with a wide mouth and divider accommodates all types of sleeping bags
  • Zippered hipbelt pockets and stretch-woven side pockets keep essentials accessible; stretch-woven front pocket with welded vent accepts Osprey AddOns™ (sold separately)
  • Compression system with 3 horizontal straps and 1 internal strap lets you securely compress the contents whether full or nearly empty, and without sag or load distortion
  • Trekking pole attachment, side gear straps, ice axe tool loops, cord loop attachment slots and removable sleeping pad straps accommodate a variety of alpine gear
  • Hydration-compatible design features reservoir sleeve and dual drink tube exit ports for on-the-go hydration (reservoir sold separately)
  • Osprey Aether 85 pack shaves weight yet remains tough with a 210-denier double-ripstop nylon and 500-denier plain-weave oxford nylon bottom
