Size is free size. This is a top-of-the-line, full-face headgear made of the finest cowhide leather from CLETO REYES, a popular and long-established Mexican brand (Rejes) in Japan. It's ideal for preventing injuries, very sturdy, and offers the strongest protection. I purchased it quite a while ago. It has only been used about a dozen times. It has no smell other than the scent of cowhide leather. - Brand: CLETO REYES - Color: Red - Design: Full-face - Material: Finest cowhide leather Thank you for looking.
