The addition of super-stretch neoprene in the arms, shoulders, and back provides complete freedom of movement for arms and shoulders, bringing performance to an all-new level. Super-stretch neoprene is softer and stretches much more in all directions with less effort. The Gladiator Pro Spring Wetsuit is flatlock stitched throughout for comfort. Smoothskin chest and back shed water and wind for extra protection. A short back zipper surrounded by super stretch makes these suits feel virtually zipperless. The Gladiator Pro Spring Wetsuit is made of 2mm neoprene with o-rings in the arms and legs.
