The Deuter Wash Bag I is a handy toiletry bag for basic hygiene items. The materials used are PFC-free. In order to ensure the water and dirt-repellent properties, deuter uses a harmless and environmentally friendly DWR (Durable Water Repellency) coating, which completely does not use PFC. This special surface treatment causes water to bead off the outside of the textiles. This keeps the material dry and nature clean.
