Using patented Direct Venting technology, eVent glove inserts provide waterproof protection and all-day comfort in the widest range of temperatures and conditions. The difference is the air permeable membrane, which instantly vents excess heat and water vapor (sweat) to keep the insulation dry and the inside of the glove warm and comfortable. Constructed with a thin nonwoven laminate and available in a full range of sizes, the glove insert allows users to maintain dexterity and agility.
