Deuter Streamer Helix Hydration Bag Valve

This deuter product is free of per- & polyfluorinated chemicals. deuter thus reduces the use of environmentally harmful substances that pollute the environment and health. PFC is used, among other things, as a coating for rain protection, as they have water-, dirt- and grease-repellent properties. Instead, deuter now uses DWR (Durable Water Repellency) impregnation that is harmless to health and the environment.
