All Energiapura catsuits are constructed from a bielastic, breathable and windproof fabric to make them as comfortable as possible. The fit and design of the catsuits have been studied in a wind tunnel for the best results, ensuring the best body adherence and a high elasticity. Energiapura's World Cup Fabric is a FIS approved material which is essential for official races. It is a three-layered bi-elastic fabric made of a polyester and Lycra blend with a polyurethane inner material. Its state-of-the-art fibres ensure exceptional aerodynamic qualities, which are the result of several years of research carried out both on the slopes and the wind tunnel.
