Compatibility and positioning
Compare the protector’s size and outline with the intended garment or fitting system. A matching brand name alone does not establish compatibility. Check the position when wearing the complete riding kit and moving into your riding posture. The protector’s own rating should not be confused with certification of an entire garment.
