To determine your helmet size, measure the circumference of your head using a measuring tape or a piece of thread. Once you have this measurement, refer to the table below to find your corresponding size. Shell SizesMost helmets use two shell sizes to cover the entire size range. If additional shell sizes are available, you can select one that better suits the circumference of your head without dealing with an unnecessarily large or heavy helmet.
