Non Wetsuit / Skins
Swimwear must be 100% textile material, which is defined as materials consisting of natural and/or synthetic, individual and non-consolidated yarns used to constitute a fabric by weaving, knitting and/or braiding.
Simply put, this would generally refer to suits made only from nylon or Lycra that do not have any rubberized material such as polyurethane or neoprene.
Swimwear must not cover the neck, extend past the shoulder, nor extend past the knees. They will not have any positive buoyancy or be insulating against the cold.
Men: a one piece brief or shorts style with leg cover not extending past the knees.
Ladies: a one piece or two piece style with no arm cover and no leg cover below the knees.
