FITS LIKE A GLOVE. To fit into our Perfetto family, a glove had better be pretty spectacular. By using reduced-seaming technology and the new GORE-TEX INFINIUM‰ã¢ WINDSTOPPERå¨ fabric, we've made a glove that is deceptively warm while staying reasonably thin and allowing maximum dexterity. We've added grip features in the palm and our Castelli Damping System for comfort. This is the kind of breakthrough glove you've come to expect from Castelli. WHAT IT IS. Futuristic thermoformed single-seam construction results in a fleece-lined glove that's windproof, water resistant, warm, slim fitting and extremely comfortable.
