This highly aerodynamic trisuit is constructed with an optimal combination of performance fabrics to achieve a tailored-fit. The shape is maintained by elastic leg grippers with dotted silicon grips on the inside of the legs. The ITU standard back zipper with cam lock makes it easy to wear and ensure the zip stays closed and the suit fits flawlessly while on the move. Performance Easy to wear for long hours in the saddle, the upper section is made of Prey fabric, lightweight, extremely aerodynamic and UV resistant (UPF 50+) with Flow inserts. An engineered rough surface of the fabric is used in the point of delamination of the airflow to reduce drag. Wind tunnel tested and race proven. Special invisible pockets for gels or energy bars. The legs are made from Fitter, a special fabric designed to reduce muscle stress thanks to its slightly compressive effect helping you perform at your best from start to finish. Comfort Designed specifically for triathlon events, the GTR chamois has a silicone gel core with strong anti-shock properties, covered with a thin fabric shield. It weighs just 42 g and doesn’t absorb water - so it doesn’t grow in dimension or weight during the swim or cause irritation in the ride. Plus an antibacterial and anti-irritation microfibre layer in contact with the skin that ensures maximum comfort on the saddle, even for ultra-endurance events. Durability Santini selects only the highest quality European fabrics. Made in Italy by Santini's highly skilled production staff. Each garment undergoes vigorous quality controls and will last a lifetime.
