What Is the Difference Between a Trisuit and a Skinsuit?

A trisuit is a one-piece race suit built to be worn through the swim, bike and run without changing, with a thin chamois you can run in. A cycling skinsuit is a one-piece aero suit built only for riding, with a thicker chamois and no design for swimming or running. For a triathlon, choose a trisuit such as the Santini Leaf. For road races and time trials, choose a cycling skinsuit such as the Santini MADSS Aerosuit V2.
