The Castelli Men's Perfetto RoS Bike Gloves are made using a futuristic thermoformed single-seam construction. New GORE-TEX® INFINIUM™ WINDSTOPPER® fabric makes these cycling gloves deceptively warm while staying reasonably thin and allowing for maximum dexterity. Castelli Damping System (CDS) was added to protect the median nerve and a neoprene stretch wrist insert allows easy on and off. The Castelli Men's Perfetto RoS Bike Gloves are ready for anything come Rain or Shine (RoS), as the name implies.
