Our warmest wetsuit, you'll have everything covered with this full-body wetsuit. 3-mm DuPont neoprene with Titanium insulation for superior heat retention. 2-mm PowerSpan in the shoulders and arms helps reduce binding. To make the Steamer easier to get on and off, we've included wrist and ankle zippers and our standard full-length, double-pull men's relief zipper. Glued and blind stitched seams help keep H2O out and heat in. Padded knees for added cushioning and durability.
