How are helmets rated?
Stilo helmets are certified to Snell SA2020, 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 SA2020. 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 Stilo 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.
