  • Features

    • G Fabric is a high-tenacity nylon fabric impregnated with silicone, so its fibers stretch under pressure instead of locking together and tearing

    • Right at your fingertips, mesh waist zippered pockets on hipbelt for stashing energy bars or gels

    • Bottom compression straps and front bungee cord allow you to lash on and carry various technical gear
    • When teammates bonk during races, use the tow loops to literally tow your teammates when in need
    • Wrapping the waist is the laminated, diecut waistbelt with zippered essentials pocket
    • Aero-Tech™ mesh on back panel helps move moisture away to keep you dry
    • Hydration sleeve with an exit port holds a reservoir (sold separately) for hands-free hydration on the trail
