Repellan® provides protection against moisture for textiles. To begin with, it's harder for rain to penetrate fabrics treated with Repellan®. Instead, moisture remains in droplet form on the fabric and can simply be wiped away or left to run off. In addition, it is proven that Repellan® treated clothes dry more quickly and retain their original appearance better than untreated textiles. The Repellan® film is also breathable - providing the underlying fabric is too. Moreover, Repellan® survives washing and dry cleaning.
