Use TX Direct for all your weatherproof gear including Gore-Tex®, Sympatex and eVENT® - in fact, anything that is designed to keep the water out and maintain breathability, unless it has a wicking lining. The treatment adds or renews water repellency and revives breathability so that your gear performs better and lasts longer. Being a wash-in treatment you can be confident that the entire garment is immersed and no areas are missed.
