Just spray this onto a fabric or surface, let it dry, and afterwards water will just roll off. It makes the surface hydrophonic (it repels water) and helps to keep you warm and dry.  This is an essential product for anyone who spends time outdoors. If the rain water rolls off your coat, it will remain breathable and condensation will not form inside your coat. You stay warmer and dryer !! Also suitable for footwear, tents and awnings, sleeping bags and car soft tops.
