Enhance the water and stain resistance of your favorite soft shell climbing and hiking outerwear without sealing in the vapor. Granger's Spray-On Soft Shell Proof repels the wet stuff but doesn't leave a residue or odor so your breathable soft shells keep the same look and feel. The difference you'll notice after applying Granger's Spray-On Soft Shell Proof is that more of the damp remains in its place of origin.
