3mm Men's Henderson THERMOPRENE Step-In Jacket The 3mm Men's THERMOPRENE Step-In Jacket is Henderson's bread and butter, because it's an all-around awesome wetsuit piece. The Thermoprene line gives the user excellent performance at a great price and all of the products in the line are constructed using Henderson's signature Thermoprene neoprene. This neoprene boasts 180% super stretch, giving the user a lot of flexibility and comfort. The neoprene is laminated with pill and abrasion resistant fabric for durability. The seams are sealed which prevent cold water from entering the suit. Edges at the cuffs are Lycra trimmed for comfort and chafe resistance.
The 3mm Men's Front Zip Step-In Jacket has full front zipper for easy entry/exit and layering. A flap of neoprene behind the zipper protects the skin and helps prevent cold water from hitting your skin, should it seep in through the zipper. Layer this product with any long john style suit for extra warmth in the water.
