Ultra-light and constructed with leading-edge Bi-Tech™ Armor Lite, the Cargo Hauler Duffel 120L is a massive gear bag, made for schlepping, heaving, and hoisting. It’s equipped with gear pockets, grab handles, and tie-down daisy chains, and has built-in maximum versatility of both ways to carry it, but also store it. It’s truly a resilient duffel bag built to do it all.
