This is a HATENKO Trakehner belt. It has only been used a few times. I used the belt without tights. The following is quoted from the website: Product Information HATENKO Trakehner Belt HT00012-09 Black Size: S-M This support belt is designed to be worn with Anglo-Arab short tights to further enhance lower back support. The upper and lower sections can be adjusted for tightening, allowing you to change the tension even during a race. It supports you in achieving your personal best by providing your preferred level of support depending on the situation. Thank you for looking. # Track and Field # Pelvic Support
