These are your cold water surf mittens, made for water 48° F and below. The Vissla Seven Seas 7mm Mitten Gloves are lined with insulation and have a smooth skin, wind-resistant exterior, and watertight cuffs so you'll be safe from the cold. The silicon palms lend to board grip and like the rest of the Vissla wetsuit line, these mittens were made using eco-friendly neoprene naturally sourced from Limestone and constructed using dope dyed yarns.
