Get the kids into the water over the cooler months with the Mad Dog Boys' Steamer Wetsuit! This wetty has a 3/2mm neoprene construction. That means it has 2mm superstretch neo in all the right places for movement and flexibility, and 3mm for the rest for warmth. It also uses textured kneepads to protect them from friction. A fantastic boys' wetsuit for some fun in the sun with the family.
