Product Description

The Mission EXP™ Hip Pack – 4.5 L isn’t your standard waist bag. Engineered for overland, trail, and travel environments, it’s made from bombproof recycled nylon with weather-sealed YKK Aquaguard® zippers and premium hardware to withstand years of punishment.

Dual Expanse BottleDrop™ Pockets expand to carry GRAYL purifiers, bear spray, or extra gear, while the BottleLock® System keeps bottles locked in place even when you’re scrambling or on the move. Inside, multiple mesh pockets, stretch slots, and a concealed valuables pocket organize essentials without wasted space.

Outside, MOLLE panels, a Velcro loop field, and a steel O-ring enable modular expansion. A heavily padded mesh lumbar belt distributes weight comfortably, even when fully loaded, with dual zippered wing pockets for small-item access.

Compact, expandable, and field-ready—the Mission EXP is purpose-built to keep your gear secure from city to summit.
