Osprey Aether 70 Pack

This lightweight mountaineering pack features a custom-moldable hipbelt and a streamlined design for backcountry pursuits. Top-loading pack shaves weight with its lightweight yet tough 210-denier high-tenacity double-ripstop nylon construction. The new AirScape Suspension uses peripheral rods, a nubbed foam back panel and an internal framesheet. Running down the sidewall, the peripheral rods anchor to load lifters and hipbelt, actively transferring load and resisting sag. Providing superior load support is the removable IsoForm CM (Custom Moldable) hipbelt, a 3D dual-density foam contoured and anatomically shaped. Osprey's certified Custom Molding available in most stores—check your local REI store for a custom hipbelt molding oven. ErgoPull hipbelt closure provides extra leverage in cinching, drawing tension along top and bottom--not through the center--relieving hipbone pressure. IsoForm dual-density foam harness with Spacer Mesh promotes airflow and wicks away moisture during warm weather and intense activity. Externally accessible bottom compartment accommodates all types of sleeping bags. Top pocket can be removed and converted into a lumbar pack; IsoForm hipbelt on pack can be removed and slid onto lumbar pack for comfortable carrying. Dual-entry side mesh pockets keep essentials easily accessible, and a built-in front mesh pocket accepts Osprey Excessories for added capacity. Front compression wings let you securely compress the contents of the pack, whether full or nearly empty, without sag or load distortion. Ski straps, ice axe tool loops, sleeping pad straps and extendable lid accommodate a variety of alpine gear. Hydration-compatible design features reservoir sleeve and dual drink tube exit port for on-the-go hydration (reservoir sold separately).
