CHOOSING THE CORRECT HELMET SIZE: Helmet fit is critical to helmet protective performance. The correct helmet size can only be checked and confirmed by physically fitting the helmet to the user. Always try the helmet on in a store, before purchasing it, to be sure you are purchasing the correct sized helmet for you. HEAD MEASUREMENT INSTRUCTIONS: Wrap a flexible tape measure around your head approximately one inch above the eyebrows and ears. Use this measurement (in either inches or centimeters) to find your helmet size. HELMET SIZING INFORMATION: To achieve proper helmet fitment, begin by finding your head circumference size using the method described. Remember that the helmet size you choose should fit around the crown of your head comfortably with no pressure points. The cheekpads should fit firmly around your face. Once your chin strap is fastened, grab the chin bar of the helmet and move it side to side. Your cheeks should move with the helmet, which should not slide across your face. Different thickness cheekpads can be purchased to obtain the best fit. Ask your dealer or visit www.thormx.com for more information.
