Mammut Hydration Bladder

The perfect hydration system for light-footed activities where your pulse does not allow you to stop. The bite valve with twist closure is leak-proof. Plus, the durable HydraPak system is 100% BPA- and PVC-free, so it can be filled with both hot and cold beverages - and the reversible pouch with removable hose makes cleaning a breeze. By the way: The slim design, specially conceived for running vests fits like a glove to Mammut's Aenergy TR5.
