For over 25 years, Stilo has led helmet innovation, and the new ST6 line moves the benchmark again. With development input from top-level programs, the ST6 brings refined front and top aerodynamics, expanded airflow, and a wider field of view to help you strap in faster and drive with more confidence.
The ST6 Offshore Composite keeps weight down while adding ventilation and clarity where it matters. From the track-tested aero to the dual-lock visor mechanism, every update is about performance you can feel in the car.
The ST6 improves on the beloved ST5 in these key areas:
Puro Tech: Stilo's composite manufacturing process minimizes excess coatings to keep mass low without compromising protection.

Added shell size: three shell sizes help deliver the smallest, lightest shell appropriate for your head size.


Increased airflow design: revised front intake and top vents route air through EPS channels to reduce sweat and keep you focused under pressure.

Expanded downward visibility: improved eyeport makes buckle fastening and cockpit checks faster during driver changes.

Interior comfort: reshaped cheek pads enhance aero stability and fit consistency at speed.

Injection-molded visor: clear optics with a washable high-performance anti-fog coating. Dual visor lock meets FIA standards in both closed and vent positions.

Updated visor hardware: smoother operation and easier installation; available in multiple anodized finishes.
Customers who typically wear a size 59 in other brands often prefer a Stilo size 61 (large shell). If you are between sizes or prefer a tighter fit, consider the smaller option.
The most effective helmet is one that fits properly. Have an assistant measure the circumference of your head about an inch above the eyebrows, around the largest point at the back, and back to the front. Take multiple measurements and use the largest.
SA2025 helmets are here, and while the changes may not be groundbreaking, they represent an important evolution in motorsport safety. According to the Snell Memorial Foundation, the SA2025 standard is an evolutionary update from SA2020—not a complete overhaul. Unlike the M2025 motorcycle standard, which adds rotational impact testing, the SA2025 auto racing helmet standard does not include rotational force requirements.
In short: SA2025 helmets are designed to offer enhanced linear impact protection, making them the safest Snell-rated auto racing helmets to date. Whether you're a competitive racer or a weekend track day enthusiast, upgrading to an SA2025-certified helmet ensures compliance with future racing regulations and gives you peace of mind at speed.
Does the ST6 Offshore Composite meet Snell SA2025? Yes, this listing reflects the SA2025 certification for U.S. auto racing.
What makes the Offshore version different? It includes noise-attenuating earmuffs designed to reduce cabin noise and improve intercom clarity.
Can I use my ST5 shields on the ST6? No, the ST6 uses its own shield system; choose ST6-specific shields and hardware.
How should I pick my size? Measure head circumference and consult the size chart; if youre between sizes, many drivers prefer the tighter option for stability at speed.
Is the visor anti-fog? Yes, the ST6 visor includes a washable, high-performance anti-fog treatment.
