Fishtail jersey made of easy-care elastic material, machine washable, with high resistance to bleaching, salt, and chlorine. The open end allows for water drainage and fast drying. It is easy to put on and take off. The monofin cover is made of neoprene used in diving sports. The patented monofin is worn like a stocking, and the soft cuffs prevent pressure points, eliminating the need for straps. This design ensures the monofin fits every foot size.
