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 in the chart below.
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 cheek pads 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, and the helmet should not slide across your face.
