  • Features

    • Contoured, anatomically curved compression molded back panel with body-mapped foam offers comfort, support and a precise fit with ventilation
    • Full-zip back panel provides duffel-style access to the pack's interior
    • Articulated Open Range hipbelt threads behind the back panel for positive load transfer to the lumbar, providing stability with flexibility for a secure, comfortable fit
    • Cut-to-fit hipbelt provides a tight wrap on your hips and eliminates gaps between your body and the pack
    • Dual hipbelt stabilizer straps allow you to adjust the upper and lower section of the hipbelt separately for a custom fit
    • Women's custom fit adjustments on contoured shoulder straps and hipbelt keep the pack flush against your torso; load lifter straps allow fine-tuning of weight distribution
    • Hoist Compression system pulls pack weight inward and upward for positive load transfer and balanced pack weight, while raising the bottom panel up to secure the load
    • Cored aluminum perimeter frame, shoulder straps and hipbelt form a fully integrated suspension system to provide more balance on uneven terrain via a positive load transfer
    • Roll-top closure and 2 side webbing buckle closures allow top-loading access to the interior and are easy to adjust with pack volume
    • Internal 3 L hydration bladder pocket has a bladder hook and discreet tube routing port; hose-keeper clip on the sternum strap keeps your water handy (reservoir not included)
    • Compartmentalized storage includes a hydration bladder pocket, 2 stretch mesh side pockets, a front quick-stash pocket and a front zip pocket with key keeper
    • Webbing and bungee cord loops on exterior of pack are ideal for stashing your trekking poles
    • Exterior also has a discreet ice axe loop, daisy chain loops for extras and a top grab handle for easy transport
    • Includes two 1.6 L removable hip pockets for stashing small items and a 7 L trash can for camp trash or collecting litter on the trail
    • Made with recycled, GRS-certified, high-tenacity nylon MIPAN® regen robic with solution dye ripstop grid
    • The tough, lightweight fabric has a 1,500 mm UTS coating that increases tear strength and durability
