CHECK THE SIZE CHART (in the image section above) The 2XU Men's P:2 Propel Wetsuit in black and textural geo is the most buoyant wetsuit from 2XU. Together with super-stretch arms and underarms, an extremely comfortable neck, rollbar and floating zip, this wetsuit has been designed to increase hydrodynamics and comfort in the water. 39 CELL is the most buoyant neoprene available with a thickness varying from 1mm to 5mm (5mm maximum permitted). Super Composite Skin coating is applied as a layer over the surface of the neoprene, creating a very unique material. The micelle structure on the rubber surface repels water when in contact with air and reduces the surface resistance when in contact with water. Low resistance allows for faster speed through the water. As a result, SCS provides comfort, extra freedom of movement, keeps the body warmer and decreases body fatigue while ensuring durability and abrasion resistance.
