    1. Fusion Flex Pro features twin removable 7075 aluminum vertical stays reinforcing a sewn-in framesheet to provide lightweight, dynamic support and to prevent winter gear from digging into your back.
    2. An anti-barreling cross-stay keeps the suspension torsionally stable and eliminates pack deformation under heavy loads.
    3. Autocant shoulder harness straps adapt to individual shoulder angles without requiring adjustment, and 3D-molded high-density LifeSpan EVA foam padding in the hipbelt increases comfort over long distances.
    4. Snow-shedding materials throughout the design allow minimal water absorption, keeping weight down and surfaces clean to prevent excess wear on outerwear.
