The Prolimit predator down-Airflex V-back zip wetsuit for men is the best suit in our advanced series. The full Airflex 500+ neoprene makes this a very flexible suit and 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 and the 5mm neoprene, keep you warm in extreme conditions. This suit has a zipper on the back with a leash for easy access.
