For the very best in comfort, mobility and protection, choose the Men's 3.0 Ultra John Wetsuit. Stretchy 3.0 mm neoprene, fleece-lined torso and double-pull relief zipper. They lined the torso and upper legs with quick-drying Checked VaporLoft™ for extra warmth and comfort, eliminating the dread of a cold, damp wetsuit in the morning. Plus, there's ThermalPlush™ lining the shoulders and lower legs. 4-way-stretch 3 mm PowerSpan™ neoprene gives you outstanding insulation, unrestricted range of motion and improved fit. Titanium-laminate adhesive reflects heat back to your body, keeping you warmer. The glued and blind-stitched seams lie smooth against your skin and slow the flow of water into the suit. Fuse Cut™ technology seals cuffs and edges without limiting the neoprene's stretch. Extra-long, double-pull YKK® front relief zipper makes it easy to "go" on the go, and 3 mm ToughTex™ pads protect your knees and covers the seat for extra durability in these high-wear areas.
