To find your approximate helmet size, use a soft sewing tape measure. Start at your forehead about one inch above your eyebrows and measure around the largest portion of the back of your head. If you do not have a soft measuring tape, use a string or phone charging cord, then lay it flat and measure it with a ruler.
