The Prolimit Predator Airflex V-Back zip wetsuit for men is a very flexible suit, the glued and blind stitched seams make sure that no heat escapes through the stitches and that the stitches are protected. The Zodiac fleece lining on the inside, the 5mm neoprene and the Full Water Block neck keep you warm in extreme conditions. This suit has a zipper on the back with a leash for easy access.
