The deuter Wash Bag Tour III is a true lightweight and offers enough storage options to accommodate all the essential toiletries. The materials used do not contain perfluorocarbons (PFCs). In order to ensure the water and dirt repellent properties of this product, deuter uses an environmentally friendly, health-friendly DWR (Durable Water Repellency) coating, which is completely PFC free. The special surface treatment makes the water beading outside the textiles. So the material stays dry and nature stays clean.
