Utilising our exclusive 50D/CK fabric we have combined a 50 denier Lycra together with a revolutionary circular knit high gauge construction, which provides the most compressive fabric on the market. Whether this garments is used on the slopes, or participating in active sports, the graduated compression of the top is fundamental to remove the waste by products the body produces during high active sport, which causes fatigue. The extra push of blood from the lower arms and back towards the heart allow this top to give you another level of performance and will allow you to perform longer with less fatigue. 2XU Compression is the new standard in high performance compression wear. Stop making compromises with second rate products that use fashion fabric and pass it off as 'performance' with big marketing words. If you're serious about getting the best compression performance on the market then make the leap to 2XU. Dozens of world champions, the Victorian Institute of Sport and a growing list of top athletes from many disciplines choose 2XU compression. Why? Because now there is a compression product that will actually meet the demands they place on it.
