"Not Your Ordinary Sweatshirt" RainSwetter? was developed by a golfer for comfort and style in rain and wind. It is perfect for all outdoor activities including golf, skiing, boating, running, hiking and other outdoor sports! Also a necessity for sports fans and for those that work in the elements. The Mooreguard TM windproof lining adds a protective barrier, eliminating the wind chill without effecting the breathable comfort of the original fabric.
