The Castelli Men’s Perfetto RoS Glove. To fit into Castelli’s Perfetto family a glove had better be pretty spectacular. By using reduced-seaming technology and the new GORE-TEX INFINIUMtrade WINDSTOPPERreg fabric Castelli made a glove that is deceptively warm while staying reasonably thin and allowing maximum dexterity. Castelli added grip features in the palm and their Castelli Damping System for comfort. This is the kind of breakthrough glove you’ve come to expect from Castelli. Fleece lined for warmth. Neoprene stretch wrist insert for easy on and off. Reflective details. Silicone zones on palm for extra. 6deg-10degC 43deg-50degF. Weight55 g.
