Simpson Helmet Fit
Author: Simpson Racing Products
- Measurement
The circumference of the head should be measured approximately one inch above the eyebrows in front and a point in the back that results in the largest measurement. Use the sizing guide to determine size.
- Try It On
Grasp the helmet by the chin strap with the front of the helmet facing you and the top down. Place thumbs on the inside surface and balance with the index fingers. Slip down over the head. If the helmnet slides down on the head with no resistance, it may be too large. Only if the helmet is impossible to to put on should you move up to the next size. The eyes should be approximately in the center of the eye port, with the top edge of the liner padding just above the eyebrows. If you will be wearing a headsock (recommended), try the helmet on with it.
- Check for movement
Check to see if the cheek pads are in contact with the cheeks. Look for gaps between the temples and the forehead pad. Check around the back for a secure fit. Have someone grab the helmet on each side and try to rotate the helmet from side to side. Note any movement of the skin as well as the resistance.
Next check the movement up and down. If in either test there was little or no skin movement and/or the helmet was moved easily, the helmet is too big. A correctly-fitting helmet should feel as if evenly distributed pressure is continuously exerted around the head. Helmets, like shoes, will break in. For this reason the helmet should fit as tight as you can stand to wear it.
- Retention check
Fasten the chin strap tightly. Have someone reach over the top of the helmet and grab the bottom edge and try to roll the helmet off. If the helmet comes off or moves
significantly, the helmet is too big.
- Now go have fun.
