For women who prefer two piece race gear, this Long Distance Tri Singlet offers the ultimate in both speed and comfort. With 2XU"s thermo-regulating ICE X fabric, extreme moisture control and ventilation is assured. ICE X fabric is engineered for endurance events like no other.

Includes built-in moisture wicking shelf bra for support and comfort.
