WindTex - WindTex is a windproof and waterproof membrane that is both light and soft for excellent comfort. It also has a high degree of elasticity, something many similar membranes lack, which allows it to move with you for a better fit resulting in greater comfort and unhindered performance. In addition, it enables maximum breathability allowing perspiration to escape without letting outside moisture in.
