Strong Athletic got the request for this shirt from Michelle P. in Anchorage, Alaska, a member of the group: "Roller Derby Injuries- Blood, Sweat, and Tears". The group is for athletes who have experienced an injury in roller derby, and recovered from that injury. Some of these skaters returned to skating and some did not. Some say that getting injured in roller derby is inevitable. Some of these injuries are visible and some are not. Roller derby has a life-long impact on the people who play the sport, and the injuries that come with the sport also can have a lasting impact for the athletes who play.
