Features
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 is available in most stores-check your local REI store for a custom hipbelt molding oven
Dual-density foam harness with spacer mesh promotes airflow and wicks away moisture during warm weather and intense activity
Suspension features a peripheral frame, 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 70 pack shaves weight yet remains tough with a 210-denier double-ripstop nylon and and 500-denier plain-weave oxford nylon bottom
