One of the major benefits of wearing an arm sleeve is the improved circulation in your arm. Sleeves are designed to provide compression to keep circulation flowing during your entire game, practice, workout, etc. Increased blood circulation can protect muscles from future injury and the sleeve will provide some support for athletes who have had a previous injury. Arm sleeves have shown to help expedite recovery for athletes. The compression helps muscles that are sore or overworked to recover faster. The sleeve enables your blood flow to circulate quicker to the heart, which helps you heal and recover quicker.
