The rider is usually required to wear an ASTM/SEI-approved equestrian helmet with safety harness fastened. Although black, velvet-covered hunt caps were once popular, the old style caps provided virtually no actual protection to the head and are now prohibited for junior riders at any time while mounted, and are not allowed on riders of any age in classes to jump. Caps are still sometimes seen on adult riders in flat classes, and remain somewhat popular at breed shows. However, many adult hunt seat riders who do not jump are also leaving behind the hunt cap in favor of ASTM/SEI-approved headgear.
