The 2XU MCS Run Compression Tights are made from a powerful graded compression material combined with the revolutionary MCS (Muscle Containment Stamping) support structure. On the inside of the tights, 2XU has developed MCS, which is a system for targeted and more powerful compression. The MCS system has extra patterns that follow the muscle structure, tendons and nerve groups on the front thighs and the calf muscle. Through this system, the tights provide even stronger pressure against the most vulnerable muscles, thus minimizing muscle stretches and injuries. The tights offer a whole new unmatched experience of support and provide protection against muscle damage during intense physical activity while being comfortable and flexible. The tights have a wider waistband, reflective logos, zippered pockets at the back and flat seams for better comfort. All of this will help make this your favourite tights.
