Made from Italian 88% Polyester & 12% Elastane Performance Wicking Fabric with UPF40. The upper suit uses a new lightweight sports fabric, lighter and thinner, which improves breathability and perspiration.                                                                                                  This Sleeveless suit offers side panels that are sewn by 4-thread cover stitch techniques, which offers comfortable fit for those long-distance events. Italian 7.5cm Italian silicone gripper provides a good fit and prevents the hem curling up.
