Gregory Fusion Flex Pro Technology


  • Fusion Flex is a lightweight, robust suspension system designed for harsh alpine environments. Its single aluminum stay and die-cut HDPE framesheet provide crucial load support while the climbing-specific hipbelt 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. A die-cut HDPE framesheet and single formed 7075-T6 aluminum center stay provide support for heavy loads, and a cross stay prevents barreling after hasty packing efforts in harsh weather. Meanwhile, the snow-shedding back panel resists moisture absorption, and removable padding in the high-cut, harness-compatible hipbelt allows for maximum weight reduction without the loss of support. Tapered, dual-density shoulder padding and an anti-slip lumbar pad maintain mobility and proper load transfer over waterproof layers.
