Water Repellent
A term applied to fabrics that have been treated with a finish which causes them to shed water but are still air-permeable. These fabrics have been treated with a finish which causes them to shed water and resist water penetration but are still air-permeable. Treatments can include wax coatings, resins, silicones, and fluorine derivatives. Such treatments do not close the pores of the fabric, while waterproof finishes do.
