The 2XU XVENT Singlet is our most minimal silhouette, perfect for trans-seasonal outdoor and year-round indoor training without ever compromising on technical features. Runners at every level need the support of highly technical apparel that allows them to focus on their time and technique. XVENT styles are fully loaed with tech: moisture wicking, quick drying, actively cooling and with custom-designed jacquard mesh panels for maximum ventilation whilst moving. This 2XU Singlet is 100% Polyester.
