*Youth SFI Helmets have a smaller, lighter shell and are designed for lower speed youth racing. Measure with a cloth tape around the head about 1" above eyebrows. A snug fit is optimum. Use size in CM for best accuracy and go with the largest measurement you get. Hat sizes are only a guideline and not the most accurate. Inches are rounded to nearest 1/16. If you are between sizes you must go with the larger size. Add 1 to 1.5cm for a head sock.

When fitting a helmet, be sure to tighten chin strap before evaluating fit.
