Ergodyne introduced a complementary piece to its Chill-Its® Hydration Pack Series. Compatible with any Chill-Its® bladder, the 5159 Hydration Pack Cleaning Kit offers an affordable, chemical-free 4-in-1 tool created to clean and maintain the bladder and delivery system. Cleaning the bladder, tubing and bite valve ensures the liquids that users drink will be clean and fresh while also preventing mold and bacteria growth.
