A wetsuit is particularly suitable for swimmers and triathletes who want to protect themselves from the cold in the water, but also to maintain buoyancy or propulsion. In general, wetsuits provide an improved water position, which should make the athlete faster. In addition, the swimming costumes have a hydrophobic (water-repellent) coating that lets you move faster through the water. In combination with the improved water position thanks to buoyancy, a wetsuit provides you with fast swimming times in competition as well as in training.
