They know what wind and rain are in Belgium and their answer is WindTex. Light and compact enough to stuff in a jersey pocket so you are prepared if the temperature drops or the skies open up, this jacket is a must have in any cyclists wardrobe.
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.
