The Classic Frogg Toggs Ladies Sweet-T (Road Toad) Rain Jacket is 100% waterproof, 100% windproof, breathable and most of all, affordable. Frogg Toggs products are constructed with a patented process of three layers of polyproylene material with a center layer of microporous film. Because the pores are 20,000 times smaller than a water droplet, moisture cannot penetrate. In addition, the new Frogg Fold seam technology offers increased seam strength without increased weight, and new waterproof taping insures that all seams keep you completely dry.
