Simply the best and most comfortable semi-dry suit made. Comfort, warmth, and fit are guaranteed thanks to Extraflex Neoprene, the new lining in Thermal Fiber, and the rear Titex Master Scuba zipper, all for a truly unique experience. Embossed Supratex protects the knees, while the seat and shoulders are reinforced with Supratex. The back along the spinal cord has a PAD Protection and a roomy 3D zippered pocket on the leg to make this suit especially suitable for heavy duty use.
