This wrist support is made with breathable mesh fabric and is one size fits all. I used it because my wrist was hurting from carrying my child. * It uses Velcro, and you can adjust the compression strength to fit your wrist size, just like taping, so it can firmly support your wrist. * By changing the way you wrap it, you can support different areas, such as the palm or the back of the hand. * It uses fabric with excellent elasticity and resilience. * Can be used on either the left or right hand.
