Sweatband strap has the function of protecting joints. Athletes are easy to be injured in high intensity sports. If it is a joint injury, it will be more serious, ranging from sprain to sports life, and wrist strap can play a role in shock absorption and protection.

On behalf of faith, many players like to print their idols or the names of people who have a great influence on them on their wristbands, which to some extent gives the players motivation on the court, and they are more confident on the court. Tatum, for example, has always claimed to be a disciple of Kobe. After Kobe left, Tatum often wore purple Kobe wristbands to express his faith.
