Smith Helmet Size Chart

Head Circumference: To determine the correct size, wrap a measuring tape around the head, keeping the tape just above the ears and level front to back. Once you've determined the measurement, you can use the chart here as a guide; however we recommend that you try helmets on prior to purchase to ensure the best fit and comfort.
