Stilo ST6 Offshore Composite SA2025: lighter, cooler, clearer
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:
- About 10% lighter than comparable ST5 models for reduced neck fatigue in long sessions
- Approximately 26% more airflow to manage heat during hot-weather stints
- Roughly 11% wider downward visibility for quicker belts and better cockpit awareness
- Refined liner and cheek pads for stability at speed and all-day comfort
- Expanded shell size range to optimize weight and fit
- Re-engineered visor for durability and easy care with a washable anti-fog treatment
- Updated visor hardware for smoother actuation and easy swaps

Stilo ST6 GT Composite Offshore Racing Helmet Sizing Note
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.
Measuring Your Head For Your New Stilo ST6 Offshore Composite Helmet
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.
What’s Changing in SA2025 Auto Racing Helmets?
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.
Key SA2025 Helmet Safety Enhancements:
- Increased Impact Protection: SA2025 helmets are required to handle slightly higher impact speeds and achieve lower maximum peak G-force thresholds across all head-form sizes.
- Global FIA Alignment: These updated requirements bring the SA2025 standard into alignment with the new FIA 8859-2024 helmet safety regulation, creating more consistency across international motorsports.
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.
