The Kriega Hydrapak is a heavy-duty, military-grade 3.75L reservoir with an insulated drink tube that is compatible with all our backpacks. The 'First Wave' reservoir is very rugged and designed for all environments and temperatures. A Wide Slide-Seal top makes it easy to fill and creates a leak-proof seal. Furthermore, the durable Hydrofusion tube has built-in foam insulation, which helps keeping your water cool in even the hottest temperatures.

The tube comes with a Surge Bite Valve with twist on/off function and protective cover to keep the bite valve clean. The Velcro connector makes it easy to attach the tube to your backpack to make sure it won't move around while riding. When you want to remove the Hydrabag from your backpack, the Plug-N-Play connect system lets you easily disconnect the drink tube (an auto shutoff valve prevents leaking) and remove the reservoir from your pack for convenient refilling. It is also fully reversible for easy cleaning, drying, and care.

Stay hydrated on any riding adventure.
