Hydration bladders and hydration packs are designed for carrying and drinking water on the move without stopping.

A hydration bladder is a flexible reservoir placed inside a backpack, allowing the user to drink through a tube while moving. This removes the need to stop or take off your pack to access water.

Hydration packs combine the bladder and carrying system into one unit, offering both water storage and space for essential gear. Typical capacities range from around 1 to 3 liters.

This makes them a practical solution for activities where continuous movement and easy access to water are important.
