As with all racing safety equipment, helmet fitment is critically important, and the helmet user can increase the risk of injury if they are not fitted properly. Please refer to the general helmet sizing chart below for proper helmet fitment. This chart is for ADULT helmet sizing only unless certain manufacturers include YOUTH/JUNIOR sizes in their chart. Otherwise, all YOUTH and JUNIOR helmet sizes will be shown below in a completely separate chart.
Properly Measuring Helmet Fitment For Roux® Helmets
- Please first refer to your hat size.
- If you do not know your hat size, use a cloth tape measure and measure around the circumference of your head, just above your brow line.
- Measure the head approximately one inch above the eyebrows across a point at the back of the head that gives the largest measurement.
- IMPORTANT NOTE: All helmets will 'Break-In' when first used. It is VERY important that the helmet fits as tight as one can comfortably withstand to wear.
