Stilo ST6 FN Composite Helmet SA2025

The Legendary Stilo FN Composite Helmet - Forever Ahead

For over 25 years, Stilo has lead the way in racing helmet innovation and the new ST6 line marks a bold new chapter. With input from Porsche and F1 teams, Stilo developed enhanced front- and top aerodynamics to deliver exceptional performance from the new Stilo ST6 line of helmets. Developed with the world's top drivers from Formula One and endurance racing, the ST6 reflects real-world needs at every level of auto racing.

The Stilo ST6 composite helmet is one of the lightest composite helmets on the market. It features enhanced airflow, visibility, and comfort while maintaining market-leading safety standards. Developed with input from the Aston Martin F1 team, every feature of the ST6 – from the track-tested aerodynamics to the cutting edge dual-lock visor system – is designed to give racers a performance edge.

The brand new Stilo ST6 helmet improves on the market-leading Stilo ST5 in every way, including the following:

• 10% lighter than Stilo ST5
• 26% more airflow than Stilo ST5
• 11% more visibility
• More comfortable liner and cheek pads
• More shell sizes for lower weight
• Improved visor construction for durability and ease of care
• Higher-quality visor hardware increases reliability

Stilo ST6 FN Composite Auto Racing Helmet Features

Puro Tech: Stilo's proprietary carbon fiber manufacturing process eliminates the need for extra lacquers and additional coatings, minimizing the weight of your new helmet. With the Puro process, Stilo delivers the lightest and safest helmet on the market.

Added Shell Size: now offered in four shell sizes, the Stilo ST6 FN auto racing helmet gives you the lightest and smallest shell size possible for your head shape.

Increased Airflow Design: by utilizing key partnerships with Formula One teams, Stilo has redesigned the ST6 front ventilation to increase airflow while maximizing safety. The new Stilo ST6 also comes standard with ventilation holes in the top, channeling airflow through the EPS foam to reduce sweat and moisture, keeping you performing at your best.

Increased Downward Visibility: with input from professional drivers around the globe, Stilo has increased the downward field-of-view of the Stilo ST6, making harness fastening easier during driver changes and giving you greater situational awareness on the track.

Interior Comfort: new and improved cheek padding in the Stilo ST6 was designed to enhance aero stability and increase comfort.

Injection Molded Visor: the brand new visors for the ST6 provide exceptionally clear visibility and are coated in a new high-performance, washable anti-fog treatment.

Dual Visor Lock: pioneering the industry, the dual visor lock on the Stilo ST6 complies with FIA standards in both the fully closed and ventilation positions.

Updated Visor Hardware: engineered for easier visor installation and smoother actuation, this visor hardware can be purchased in a variety of anodized finishes.

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.

Measuring Your Head For Your New Stilo ST6 FN Composite Helmet

The most effective helmet is one that fits properly. To measure your head, have an assistant use a dressmaker's tape or a piece of string to measure the circumference of your head. Start at a point about an inch above your eyebrows, looping around the back of your head at the point that results in the largest measurement, and finally around to the front again. It's a good idea to take two or three measurements to make sure you have the largest one.
