Features
45L women’s pack with adjustable, lightweight features designed for all-day comfort and through extended overnight pursuits
Comfort and support through contoured, anatomically curved back panel with body mapped foam for a precise fit with ventilation. Full-zip back panel provides duffel-style access to the pack interior
Secure, comfort fit with articulated Open Range Hip Belt that threads behind the compression molded back panel for positive load transfer to the lumbar, providing stability with flexibility
Cut-to-fit hip belt provides a tight wrap on hips and eliminates gaps between body and pack. Dual hip belt stabilizer straps allow the upper and lower section of the hip belt to be adjusted separately for a custom fit
Women’s custom fit adjustments on contoured shoulder straps and hip belt keep pack flush against your torso. Load lifter straps allow fine tuning of weight distribution
Balanced pack weight is achieved through our unique Hoist Compression system that pulls pack weight inward and upward for positive load transfer, while raising the bottom panel up to secure the load
Cored aluminum perimeter frame, shoulder straps, and hip belt function as a fully integrated suspension system that provides more balance on uneven terrain through a positive load transfer
Top-loading access to interior with roll-top closure and two side webbing buckle closures that easily adjust with pack volume
