Built with a split-finger design for rides in freezing cold, wet, and windy conditions, the Giro 100 Proof Gloves are Giro's warmest gloves ever and equipped with low-profile weatherproof materials that won't weigh you down. Weatherproof, breathable outer shell has zippered pockets for hand warmers when temperatures plummet. PrimaLoft and Thinsulate XT-S form an insulated core for maximum warmth while the interior lining uses X-Static AGrid antimicrobial thermal fleece with silver fibers to hold onto heat. Reflective fabrics and highlights keep you visible in low light. Touch screen details make it easy to answer your phone without removing your gloves. Clarino palm provides a secure grip and extended Merino wool cuff keeps the cold out.
