While Castelli is best known for innovative hyper-performance clothing, this jacket shows that our expertise and attention to detail make a difference even on a simple, basic winter jacket. We\'ve chosen fabrics that we know provide the best mix of warmth and breathability, using GORE-TEX INFINIUM™ WINDSTOPPER® on the front, with a luxuriously warm brushed-fleece liner, while the back is in our Warmer fabric, which lets excess heat and sweat easily escape while keeping you warm. We\'ve given it a neutral fit, not as tight as our race-fit extreme technical pieces but close enough to prevent cold air from filling the space between jacket and body. It features silicone gripper elastic, generous reflectivity in the back and a quality YKK® Vislon® zipper. What It Is The perfect jacket for mild winters or for the rider who tends to overheat, this piece features our warmly insulated GORE-TEX INFINIUM™ WINDSTOPPER® fabric on the front and sleeves while the back forgoes the membrane to let moisture escape. It\'s a non-race-fit jacket to fit most body shapes.
