Osprey UNLTD AntiGravity 64 Women's Internal Frame Backpack (Clearance)

Osprey's revolutionary AntiGravity Suspension system delivers an unparalleled balance of support and ventilation and the UNLTD AntiGravity 64 Women's pack takes that design to the next level. With state-of-the-art fabrics, one-of-a-kind technology, and never-before-seen 3D printed lumbar support, the pack is equipped with every feature you could possibly want for extended backpacking trips and loads of up to 55 pounds.

An engineering work of art as much as a carrying system, Osprey's women's-specific AntiGravity Suspension system equips the pack with weight-carrying efficiency, maximum breathability, and a contoured fit that'll nearly make you forget you have it on your back. A complex panel of tensioned meshes extend from the top of the backpanel down to the 3D-printed FitScape lumbar pad and out to the sides of the hipbelt. This structure contours automatically to the body and flexes as needed to provide outstanding fit and unrestricted movement. Additionally, an anodized 7075 aluminum alloy frame provides vertical stiffness to further support the weight being carried. Two stainless steel wires at the bottom of the frame deliver spring tension to the hipbelt to allow for independent movement and to maximize balance and load stability. An AutoLift system engages the upper frame, so you don't ever have to readjust load lifter straps while on the move. Self-locking cams enable you to make torso length micro adjustments while wearing the pack to ensure that the backpanel sits properly and comfortably against your back. The 3D printed FitScape lumbar pad supports weight while reducing pressure points and has an open structure to offer ventilation as well as a polymer compound that gently grips your back to help keep your load stabilized. The padded Fit-on-the-Fly hipbelt with an intuitive ErgoPull closure and a positioning sternum strap provide further fit adjustability.

Accommodating backpackers of different heights and torso lengths, the pack is available in your choice of Xsmall/Small (best fits torsos ranging from 13.5"-17") and Medium/Large (16"-19.5") size options.

The pack's top-lidded large main compartment has a unique zippered "clamshell" opening that makes for easy opening and loading. There's also a large U-shaped zippered opening on the face of the pack to gain wide-open access to the interior. An interior divider sleeve equipped with built-in compression allows you to utilize the lowest portion of the packbag as a dedicated sleeping bag compartment. The pack's lid has two zippered compartments that offer additional storage. It can be removed entirely to shave weight or for use independently as a fully-functional, hydration-compatible lumber pack (hydration system not included). Two large-capacity zippered external pockets offer a ton of storage that can be easily accessed without getting all the way into the main compartment.

Other features include integrated compression straps, large zippered hipbelt pockets, webbed ski loops, tuckaway ice axe loops, removable sleeping pad straps, a sternum strap buckle that doubles as a safety whistle, a convenient Stow-on-the-Go trekking pole attachment system, and an externally-accessed reservoir sleeve (hydration system sold separately) with injection-molded hose routers on the shoulder straps.
