Run longer and recover faster with 2XU's MCS Run Compression Shorts. Featuring reflective logos for visibility and three rear zip pockets to hold your phone, cards, keys, gels and any other essentials. Designed specifically for runners who want to go the distance, Muscle Containment Stamping (MCS) provides run-specific muscle support to quads - which helps support knee joints, reduce ground reaction force, and muscle oscillation. The results? Improved alignment, increased agility during your run - and faster recovery after your run. Constructed in 2XU's signature PWX (Power-Weight-Flex) fabric, these tights are the premium choice to maximize your running performance.
