2XU has been designing compression clothing for athletes since before there was compression clothing for athletes. It hasn't rested on its laurels, though. 2XU constantly pushes the science of compression forward to increase athlete performance and reduce injuries caused by high impact workouts. The 2XU Elite MCS Compression Short takes compression to the next level with its revolutionary Muscle Containment Stamping system, which targets specific, high risk areas of your legs and protects them while increasing your overall power and performance. The Elite MCS compression Short is made with Invista Lycra for exceptional fit, support, and recovery. High filament yarns quickly pull moisture away from your skin and move it to the outside surface of the fabric. The antibacterial fabric helps to manage odors and provides UPF50 sun protection. Flatlock seams throughout its construction eliminate chafing and irritation. A drawstring waist offers a secure, adjustable fit.The big story here, however, is Muscle Containment Stamping. MCS specifically targets muscles, tendons, and fascia groups that are commonly damaged during high impact workouts. This revolutionary fabric support system focuses greater compression power to wrap precise areas and reduce muscle oscillation and damage. Front panels are built with 70D PWX fabric, while the rear panels use powerful 105d PWX fabric for added support for the hamstrings.The results are dramatic. 2XU's MCS compression system delivers greater power output, reduced long term overuse injuries, faster warm up time, and heightened proprioception awareness of limb placement for agility.
