The Carqon rain tent is made of a sturdy nylon with water-repellent coating. This material is often used in water sports and is water resistant to make sure the box will stay dry during rainfall. 

If you want to clean the raintent, we advise you to take off the raintent from the bike, and clean it on a flat surface. This is to avoid pressing too hard on the window foil, which is logically more vulnerable than the nylon fabric.
