Waterproof fabrics are specially designed materials that prevent water from penetrating through them. These fabrics are often used in outdoor gear, such as jackets, tents, and footwear, to keep users dry in wet conditions. They are typically made using coatings or laminations that create a barrier against moisture. Common types of waterproof fabrics include Gore-Tex, PVC, and nylon. Each type has unique properties, such as breathability and durability, making them suitable for various applications. Waterproof fabrics are essential for activities like hiking, camping, and sailing, where exposure to rain and water is likely.
