The O'Neill Psycho Tech 7mm Mitten wetsuit gloves are new for winter and feature the amazing Technobutter 3 neoprene which is O'Neill's most flexible, warm and light material. This means you get the best in term of restriction free movement when you are in the water. The benefit of wearing a mitten is that all you fingers are together so they are better at retaining heat than gloves. A 7mm mitten is for someone that really feels the cold and wants the best in warmth.
