A hydration pack is a type of hydration system built as a backpack or waistpack containing a reservoir or "bladder" commonly made of rubber or flexible plastic. The reservoir contains a capped mouth for filling with liquid and a hose that allows the wearer to drink hands-free. Some hydration packs are insulated to keep water from freezing or becoming warm. Reservoir sizes commonly range from 1.5 to 3.0 litres. Hydration packs are commonly used for outdoor recreational activities, such as camping, hiking, bicycling, and kayaking, as well as for military maneuvers.
