Unbeatable functionality combined with unique style is what makes the POW Royal GORE-TEX® Mittens so darn sick! They're constructed with premium water repellent goat skin leather and durable micro-twill nylon, and fully loaded with a GORE-TEX® water and windproof insert, plus 3M™ Thinsulate™ insulation. It's hard to even imagine just how warm and comfy these really are. If you are into hitting the snow when everyone else is sitting by the fire, you need a mitten that will do the same.
