PolarProof, a wash-in treatment for fleece, wool, synthetic insulated skiwear & outerwear, applies an even coating of durable H2O-repellency to the entire garment. Treated items dry remarkably fast, insulate substantially better in wet conditions and remain breathable after treatment. New, more concentrated formula treats more garments per bottle. (For WINDSTOPPER fleece, use TX-Direct Wash-In).
