Waterproof and breathable fabrics are among the lightest and highest performance fabrics for the outdoor gear industry. If you are looking for a very light weight product but not necessarily the highest durability, then this type of fabric is for you. Our 10 denier WPB 1.4 oz. is great for use in products such as ponchos, pants, bivy shells, jackets, and other items. Cleaning and maintenance our waterproof/breathable fabric is easy with a damp cloth or maintaining with a waterproof spray such as ReviveX Durable Waterproofing spray.
