The GatorSkins® technology was developed by DuPont researchers from a new leading edge material. This micro fabric is knitted from ultra microfibers that are smaller than a human red blood cell, yet they hold a greater amount of warm air next to the body than traditional fabrics of equal or greater thickness. GatorSkins® will keep you warmer in the cold and drier in wet weather and still breath better than any other water repellent material you’ve tried.
