Chill-Its 5160 Hydration Pack delivers reliable hands-free hydration for demanding work environments and outdoor activities. Designed for comfort, durability and easy maintenance, this hydration system keeps water accessible throughout long shifts, hikes, rides and high-heat conditions.

The backpack features a lightweight, low-profile design that contours comfortably against the back for balanced weight distribution and reduced bulk during movement. Breathable mesh padding, adjustable shoulder straps and a buckle chest strap provide stable all-day comfort, while rugged ripstop polyester construction delivers long-lasting durability. Reflective accents increase visibility in low-light environments and attachment loops offer convenient storage for gloves and accessories.

The 3.0L hydration bladder includes a wide fill port for quick, mess-free refills with water or ice. An internal baffle helps reduce sloshing for a smoother carry, while clear tubing allows easy inspection and cleaning. The twist shutoff mouthpiece provides controlled hydration and features antimicrobial treatment with a protective cover to help keep the drinking surface cleaner throughout the day.

Replacement parts, including 5052 Bladder and 5053 Mouthpiece, help extend the life of the hydration system with easy-to-install replacement components built for continued performance and simple maintenance.
