Kriega 3.75 Liter Hydrapak Shape-Shift Reservoir 

The Kriega HydraPak is a heavy duty, military grade reservoir and insulated drink tube that is compatible with Kriega TRAIL 9 and TRAIL 18 Adventure Backpacks.

The 0.4mm thick Thermo Polyurethane (TPU) is twice the thickness of standard consumer models. Fully reversible for easy cleaning and drying, the Wide Slide-Seal top makes it easy to fill and creates a leak-proof seal. The Hydrofusion tube is durable and lightweight with built-in foam insulation helps keep your water cooler in even the hottest temperatures. The Surge Bite Valve is an ergonomic design with twist on/off function and protective cover. A Plug-N-Play connection system lets you easily disconnect the drink tube (an auto shutoff valve prevents leaking) and remove the reservoir from your pack for convenient refilling while leaving the drink tube in position.
