When training days stack up and recovery matters, the 2XU Men's Core Compression Long Sleeve delivers targeted support to help you keep moving strong. Designed to provide compressive muscle support and improve recovery time, PWX fabric with circular-knit 360-degree stretch allows you to move freely while supporting key muscle groups to keep you performing at your best and reduce the risk of injury. Breathable mesh panels through the center back and under the arms increase airflow to help regulate body temperature, preventing overheating as you move. Quick-drying fabric pulls sweat away from your skin, keeping you dry, comfortable, and ready for whatever the day brings.
