The deuter Wash Center I is a toiletries bag for holiday-makers who love well-organised travel and want a clear overview of their personal hygiene items. PFC-free materials. To maximise water and dirt-repellent properties, deuter uses a non-toxic DWR (Durable Water Repellency) coating that is harmless to both health and the environment. Does not contain any PFCs. This special surface treatment causes water to bead up on the outside of the fabric. The treatment is not only environmentally friendly, but also keeps the material dry.
