The Vissla Seven Seas 3mm Gloves are designed for surfers who don't like wearing gloves because these mitts feel more natural in cold water thanks to the 3mm of neoprene in a tailored fit. Naturally, they provide a bit of warmth for those chilly mornings with insulation that heats and a full thermal lining that dries fast so you don't have to worry about putting on cold wet gloves. Watertight cuffs keep water out so your hands stay warm and dexterous in cold water: 49 - 58° F / 9 - 14° C . And just like the rest of the Vissla wetsuit line, the Seven Seas Gloves are eco-friendly with naturally sourced Limestone and scrap rubber tires for the neoprene, dope dyed yarns, and responsible textile production.
