How are helmets rated?

Simpson helmets are certified to Snell SA2015, SFI, FIA 8859 and 8860, CMR, DOT and ECE standards.

Auto racing helmets are rated as either M, SA or K.

  • The most current Snell rating is SA2015. SA stands for Special Application. SA-rated helmets are used in competitive automobile racing and require a fire-retardant rating.
  • M stands for motorcycle or motorized vehicles. M-rated helmets are used for racing vehicles that do not require a fire-retardant rating.
  • K- and CMR-rated helmets are used for karting applications and are not required to be fire retardant. Please refer to your sanctioning body rulebook.

How do I measure my head for a helmet?

Using a cloth tape measure, measure around your head, beginning right above the brow and continuing around the widest part of the back of the head. See our size chart for conversions in both hat sizing and XS-XL.

How should my helmet fit?

Your helmet should fit tightly to your head without being uncomfortable. It should be well-seated at the crown and you should feel contact with even pressure around your head. Cheek and ear areas can be custom fitted.

When should I replace my helmet?

Snell recommends you replace your helmet every 5 years. Your helmet should be inspected by a professional following any impact. Remember, you only have one head and racing is a dangerous sport. If you are in doubt regarding your helmet’s performance and integrity, get a new one.

Does Simpson re-line helmets?

Yes. The helmet must be Snell SA2010, Snell SA2015, or an FIA certified Simpson helmet to be relined. The cost is $150. Helmets must pass inspection by our technicians before we replace the interior. Shipping charges are the responsibility of the customer.

Does Simpson install head restraint anchors on its helmets?

Yes. We install head restraint anchors on new, full-face helmets. Please order at time of purchase. An installation fee will apply.
