Made from limestone based 100% super stretch neoprene, these 5mm Vissla 7 SEAS Claw Wetsuit Gloves will be the enemy of cold water temps! These superfit gloves have a wind-resistant duramax smooth skin exterior but are fully lined with a thermal hollow fiber lining which insulates heat and dries fast. Other features include: a Silicon board grip in the palms, a watertight cuff, and sealed seams with Taitex externally to really keep the cold water out.
