The 2XU Men's Light Speed Compression Short is a tight, fitted short with compressive qualities that provide muscle protection, support, and comfort. Powerful compression is supplied to the abductor and quad, while the glute and hamstring are also supported during your run. MCS technology gives increased support to the quad in order to reduce muscle oscillation and damage. The stretch fabrication also wicks moisture away from the body to keep you dry, while flatlock seams prevent you from chafing. You will feel and smell fresher for longer thanks to anti-bacterial properties within the fabric, and with UPF 50+ built in, you will be protected from the sun's harmful rays.
