The 2XU Propel Open Water neoprene suit is specifically designed for swimming and training in open water as safely as possible. The durable laminated bright green nylon neoprene across the back panel, the lower arms, and legs ensures that the user is extremely visible in open water. The premium soft skin neoprene is buoyant yet flexible and varies in thickness throughout the body of the neoprene, which displaces the centre of buoyancy lower down, preventing the legs from sinking and placing you in a perfect horizontal swimming position. The Super Composite Skin (SCS) hydrodynamic coating reduces surface resistance to increase speed. The floating zipper panel enhances movement to improve stroke distance. The often-overlooked inner lining has been designed with 520% elasticity to ensure comfort and low absorption.
