Fusion Flex is a lightweight, robust suspension system designed for harsh alpine environments.

Its tubular 7001 aluminum perimeter frame and perforated HDPE frame sheet provide crucial load support and optimal torsional flexibility while the climbingspecific hip belt and harness maintain comfort for technical ascents.

Fusion Flex combines crucial load management, and simple, durable design to offer climbers the ideal alpine-minimalist pack suspension system. Combined with its lightweight, reinforced perimeter frame a cross-stay prevents barreling after hasty packing efforts in harsh weather. Meanwhile, the snow- hedding back panel resists moisture absorption, and removable padding in the high-cut, harness-compatible hip belt allows for maximum weight reduction without the loss of support. Tapered, dual-density shoulder and lumbar padding maintain mobility and proper load transfer over waterproof layers.
