Cold Go Away: The main purpose of the wetsuit is to keep your children warm in the water. Wetsuit works by trapping a thin layer of water between the neoprene and their skin so they are going to get wet(hence the name, wetsuit). The water between the skin and the wetsuit will form a thermal isolation layer, which will prevent the heat generated from their body spreading out, that keeps them warm..Full Protection from Damage and Sunlight: Wetsuit will provide a protective barrier from stinging sea creatures and help prevent cuts and stings due to accidental contact with underwater environments such as a reef. And it also protects your children's whole body against the sun if they wear a full wetsuit..Easy to Wear Even for A Child: We choose to open the zipper in the back side, which is a traditional zipper-type that have vertical zip on the back of the suit which runs down the top down to the waist. The back zipper is normally opened wider than front one, thanks to that, donning on and off will be much easier. They can easily put on and take off the wetsuit without the help from yours..Long Lasting Nylon Material: Wetsuit typically has three layers. Neoprene is the thickest and middle layer and the thicker the neoprene, the better the suit is at keeping you warm. The layer closest to them is made of soft nylon to protect their skin against chafing which will happen if a tough material is used. The outermost layer is also made of nylon which will last longer than other materials..Brand XUKER Service: We are always committed to provide the best product for our customer at a competitive price.
