Daytona Viper Helmet Sizing Guide

Let's find Your Correct Helmet Size! Please keep in mind helmet sizes vary widely by Manufacturer. Measuring your head is a starting point to determine what helmet size to order. However, this is not the only factor. Please read on !

To find your helmet size, you will need a tailor's tape measure to measure your head. To determine the most accurate head measurement, you will also need someone to assist you with the measurement. Have your assistant place the bottom of the tape measure approximately ½ inch to 1 inch above the eyebrows in front and back of the head a point that results in the largest possible measurement. Take several measurements to make sure you have an accurate head measurement. Remember your goal is to order the proper size helmet. 

Use Daytona's size chart only as a guide before ordering.  For best results, if you find you are between the smaller and larger measurement for any particular size, we recommend ordering One Size Larger than Daytona's sizing chart recommends.
