What others say about Kriega's Hydrapak: 'This is the best system I have found. Been using hydration packs since the first days of Camelback. The Kreiga system blows them out of the water. Just like all the other Kreiga products, there's no comparison with anything else out there, they are the class leaders. Absolutely worth every penny...'
The 'First Wave' (military spec.) reservoirs are designed for extreme environments. The 0.4mm thick Thermo Polyurethane (TPU) is twice the thickness of the standard consumer model. Fully reversible for easy cleaning / drying. A 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, this simple, but breakthrough tube helps keep your water cooler in even the hottest temps.
Surge™ Bite Valve naturally ergonomic design with twist on/off function and protective cover.
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 while leaving the drink tube in position.
