Lightweight Fiberglass/Kevlar Multi Sandwich Fiber Shell The Stilo ST5 GT Composite features an advanced Fiberglass/Kevlar Multi Sandwich Fiber (MSF) shell designed to balance structural strength, impact-energy management, and helmet weight. Its composite shell construction uses multiple reinforcing materials arranged to provide the protective performance required by Snell SA2020 and FIA 8859-2015. Stilo manufactures the composite shell using an autoclave molding process designed to deliver consistent construction and strength throughout the helmet. The ST5 GT Composite offers a premium alternative to conventional fiberglass racing helmets while maintaining a comfortable, manageable weight for extended driving sessions. Snell SA2020 and FIA 8859-2015 Racing Certification The Stilo ST5 GT Composite carries two recognized automotive motorsport safety certifications: Snell SA2020: Automotive racing helmet certification addressing impact performance and other motorsport-specific safety requirements. FIA 8859-2015: FIA homologation for racing helmets used in approved motorsport applications. These certifications make the ST5 GT Composite suitable for numerous road racing, club racing, track-day, and endurance racing applications where the relevant standards remain accepted. Important: FIA 8859-2015 is not the same as FIA 8860-2018. Racing organizations establish their own accepted certification standards and expiration requirements. Always verify helmet eligibility before competition. Large Eyeport for Exceptional Driver Visibility Visibility is one of the defining characteristics of the Stilo ST5 GT Composite. Its generous eyeport design provides excellent peripheral vision, allowing drivers to maintain greater awareness of mirrors, approaching competitors, dashboard instruments, and cockpit surroundings. The expanded opening is particularly valuable for GT and endurance racing, where situational awareness is essential when navigating traffic and monitoring vehicle information. The helmet's eyeport design also supports Stilo's extensive selection of replacement visors and optical accessories. 3mm Clear Anti-Fog Racing Visor The ST5 GT Composite includes a 3mm clear visor with anti-fog treatment designed to help maintain visibility in changing cockpit conditions. Stilo's central visor locking mechanism provides an accessible closure point that can be operated while wearing racing gloves. The ST5 visor platform supports multiple optional shield finishes, allowing drivers to tailor their setup for different lighting conditions. Compatible options may include clear, smoke, mirrored, and iridium finishes, depending on availability. Explore the Stilo ST5 and ST5.1 Replacement Helmet Shields for additional options. Integrated Side Ports for Maximum Customization One of the ST5 GT Composite's most distinctive features is its integrated side accessory port system. Unlike conventional racing helmets that may require external accessory mounting arrangements, Stilo designed the ST5 shell with dedicated side ports that accommodate compatible components while maintaining a clean helmet profile. Depending on the selected installation, the helmet can accommodate: Integrated communication electronics Compatible microphones and speakers Radio and intercom connection systems Driver hydration equipment and drinking tubes Side-air ventilation accessories Compatible air-cooling systems This modular configuration makes the ST5 GT particularly useful for endurance racing teams and drivers who need to customize their helmets for different vehicles. Communication electronics, hydration systems, air accessories, and other optional equipment are sold separately unless specifically included in the selected configuration. Noise-Attenuating Earmuffs for GT and Endurance Racing The Stilo ST5 GT Composite includes removable noise-attenuating earmuff cushions designed to reduce unwanted sound inside noisy competition vehicles. By creating additional isolation around the ears, these cushions can help improve driver comfort during extended racing sessions. They also provide a useful foundation for compatible integrated communication systems, allowing microphone and speaker equipment to be installed according to driver preference. For endurance racers, effective sound management can make radio communication easier to understand during long stints. Removable Cheek Pads and Adjustable Interior Fit Proper helmet fit is essential for protective performance, comfort, and stability. The ST5 GT Composite incorporates removable cheek and crown comfort padding, allowing compatible interior components to be exchanged when appropriate. This flexibility enables drivers to fine-tune the helmet's fit without compromising the integrity of the protective shell. The black Nomex interior provides fire-resistant materials suitable for automotive motorsport applications. Stilo's Intermediate Oval interior shape is designed to provide secure contact around the head while accommodating a broad range of drivers. Replacement pads must be selected specifically for the ST5 helmet platform and installed according to manufacturer recommendations. Two Shell Sizes for Reduced Weight and Bulk The Stilo ST5 GT Composite uses two exterior shell sizes to provide more proportional helmet dimensions across its available size range. The smaller shell accommodates helmet sizes 54, 55, 57, and 59, while the larger shell accommodates sizes 60, 61, 63, and 64. This approach helps reduce unnecessary exterior material around smaller head sizes while providing adequate interior dimensions for larger drivers. The transition between the small and large shell occurs at size 60, making it particularly important to evaluate fit when selecting between sizes 59 and 60. M6 HANS and FHR Anchor Compatibility The Stilo ST5 GT Composite includes factory-installed M6 threaded mounting receivers designed for approved Frontal Head Restraint hardware. These threaded mounting points allow compatible HANS and other FHR anchor posts to be installed without modifying the helmet shell. Important: M6 threaded receivers are included, but HANS/FHR anchor posts are sold separately unless specified in the selected package. Always use approved anchor hardware and follow the installation requirements of the helmet and head-and-neck-restraint manufacturers. Optional Forced-Air Cooling and Hydration Systems For drivers competing in hot environments or extended endurance races, the ST5 GT Composite can be configured with compatible Stilo ventilation and hydration accessories. Available configurations include selected side-air and top-air systems that can help introduce external cooling air into the helmet. Hydration accessories allow compatible drinking tubes to be routed through the helmet's integrated accessory system. The helmet's modular design helps keep these systems organized while reducing interference with the driver's comfort padding and cockpit equipment. Air-cooling hardware, hydration components, and external cooling equipment are available separately.

(1230 g) up to size 64 with intercom These exceptionally low weights make the ST5 GT ZERO a premium option for racers who place a high priority on reducing helmet mass. Purpose-Built for Closed-Cockpit Racing The GT configuration is designed around the needs of drivers competing inside closed-cockpit race cars. Its aerodynamic shell, integrated accessory ports, ventilation capability, communication compatibility, and excellent eyeport visibility make it particularly well suited to GT, endurance, touring-car, prototype, and sports-car racing. Dual Integrated Side Ports One of the ST5 GT's most distinctive features is its pair of integrated side ports. Instead of attaching large external fittings to the helmet, Stilo incorporates the accessory connection points directly into the shell design. The side ports can be configured for several types of driver equipment, allowing the helmet to be tailored to the car and racing application. Side Port Accessory Options Integrated communication electronics Forced-air helmet systems Driver hydration systems Helmet Eject system integration Radio and communication connections When an accessory is not installed, the ports remain discreet and integrated into the helmet profile. GT vs. Naked ST5 ZERO The ST5 GT ZERO includes Stilo's multifunction side ports for electronics, air, hydration, and other accessories. The ST5 N ZERO, often referred to as the Naked version, removes the side-port system for drivers who prefer the cleanest and simplest possible shell configuration. Larger Eyeport for Improved Visibility The ST5 platform features a taller and lower eyeport than previous-generation Stilo helmets, providing improved visibility without sacrificing the coverage expected from a professional full-face racing helmet. The increased viewing area helps drivers see more of the cockpit, mirrors, gauges, apexes, surrounding traffic, and track environment. Center Pinch-Clip Visor Latch The ST5 visor uses Stilo's convenient center pinch-clip locking system. The centrally positioned latch is designed to make visor opening and closing easier, even while the driver is wearing racing gloves. This placement also allows the visor to be operated naturally with either hand. ST5 Visor Compatibility The ST5 GT ZERO uses the standard Stilo ST5 visor family, giving racers access to a wide variety of shield options for different lighting and weather conditions. Available ST5 shield options include clear, smoked, mirrored, colored, and other specialty configurations. Eight Top Ventilation Openings The ST5 GT ZERO includes eight top ventilation openings designed to help move cooling air through the helmet and reduce heat buildup during demanding sessions. These openings can also be used with compatible Stilo ST5 Top Air systems when forced-air cooling is desired. Forced-Air System Compatible For hot closed-cockpit cars, the ST5 GT ZERO can be configured with a compatible forced-air system. The helmet's integrated design allows air-system hardware to be added without turning the helmet into a bulky collection of external fittings. This makes the GT ZERO especially attractive for endurance racers and drivers competing in high-temperature cockpits. Integrated Communication Capability The ST5 GT platform was designed to accommodate professional racing communications. Compatible microphones, speakers, earbuds, radio connections, and other electronics can be integrated into the helmet depending on the driver's communication system. This approach helps keep wiring organized while maintaining the comfort and fit of the interior. Hydration System Compatible The ST5 GT ZERO can also accommodate a compatible driver drinking system through its integrated accessory architecture. For endurance racing and long sessions, hydration-system integration allows the driver to drink without removing safety equipment or relying on awkward external routing. Eject System Compatible The helmet can be configured for use with a compatible Eject helmet-removal system, providing teams and safety crews with another option when preparing the driver's complete safety package. Factory HANS Anchors Included The ST5 GT ZERO includes HANS/FHR post anchors, allowing the helmet to be used with compatible Head and Neck Restraint systems. Having the anchors installed as part of the helmet package simplifies race preparation and ensures the helmet is ready for the restraint equipment commonly required in professional motorsport. Contoured ST5 Cheek Pads The ST5 interior uses redesigned, contoured cheek pads developed to improve comfort and helmet stability. A proper racing helmet should remain firmly positioned on the head during braking, cornering, vibration, and aerodynamic loading without creating excessive localized pressure.

The ST5 GT ZERO is built for the racer who wants the integrated functionality of the ST5 GT platform without giving up the weight advantage of Stilo's ZERO carbon construction. Its combination of FIA 8860-2018 protection, low shell weight, integrated communication and cooling options, excellent visibility, and HANS compatibility makes it especially well suited to demanding GT and endurance applications. Getting the Correct Stilo Fit A properly fitted racing helmet should feel snug and secure around the entire head with even pressure and no concentrated painful areas. Measure around the widest part of the head using a flexible measuring tape, approximately one inch above the eyebrows and around the rear of the skull. Take two or three measurements and use the largest consistent measurement when selecting a helmet size. Drivers moving from another helmet brand should select their Stilo size according to actual head circumference rather than assuming the same numerical size will fit identically. Stilo Size 59 Fit Note We have found that customers who normally wear a size 59 in other helmet brands are often more comfortable in a Stilo size 60, which moves the driver into the larger shell. Please measure carefully and order accordingly.

Stilo ST5 FN 8860-2018 ABP Carbon Fiber Racing Helmet FIA 8860 Certification valid thru 2033 for these ST5 FN 8860 ABP Helmet The Stilo ST5 FN 8860-2018 ABP Carbon Fiber Racing Helmet is engineered for professional drivers who demand one of the highest levels of helmet protection available in motorsports. Designed around the stringent FIA 8860-2018 ABP standard, the ST5 FN ABP combines an extremely lightweight carbon-fiber shell with Advanced Ballistic Protection developed for top-level open-wheel, prototype, endurance, and professional racing. The FN designation stands for Stilo's Formula Naked configuration. Unlike the ST5 GT, the FN eliminates the external integrated side ports to reduce weight and create an exceptionally clean aerodynamic profile. The helmet can still be configured for communications, forced air, hydration, and helmet eject systems through Stilo's purpose-built accessory system. For drivers competing at the highest levels of motorsport—or racers who simply refuse to compromise on protection—the ST5 FN 8860-2018 ABP delivers exceptional safety, low weight, comfort, and professional-grade functionality. FIA 8860-2018 ABP Advanced Ballistic Protection ABP stands for Advanced Ballistic Protection. FIA developed the ABP specification to provide increased protection to the frontal area of the helmet, particularly around the forehead and visor opening. The ABP design incorporates additional protection directly into the helmet structure instead of relying on the separate Zylon visor panel used with previous-generation FIA 8860-2010 Formula 1 helmets. The FIA 8860-2018 ABP testing procedure includes demanding impact and projectile testing intended for motorsports where drivers may be exposed to debris and other high-energy impacts. The result is an exceptionally protective helmet designed for the highest levels of professional competition. Lightweight Carbon Fiber Construction The Stilo ST5 FN 8860-2018 ABP is constructed from 100% medium-tensile carbon fiber, providing an outstanding combination of strength, rigidity, impact performance, and low weight. Reducing helmet weight is especially important in open-wheel and high-downforce race cars, where sustained lateral G-forces can place significant loads on the driver's head and neck. The lightweight construction of the ST5 FN helps reduce fatigue during long sessions without sacrificing the protection required by the FIA 8860-2018 ABP standard. Designed for Open-Cockpit and Professional Racing The ST5 FN ABP is particularly well suited for open-wheel and open-cockpit racing where the driver's helmet is more exposed to airflow, debris, and other environmental factors. The ABP configuration uses a reduced-height eyeport and specialized visor to increase protection around the forehead area. Combined with the aerodynamic ST5 shell, the helmet provides a compact and streamlined profile for high-speed racing. Formula Naked FN Design The FN or Formula Naked configuration removes the external side accessory ports found on the Stilo ST5 GT. Eliminating these ports reduces weight and creates a smooth exterior shell ideally suited to Formula, prototype, and open-wheel applications. Despite the clean exterior, the ST5 FN remains compatible with a wide range of Stilo accessories and can be configured for driver communications, hydration, top forced air, and helmet eject systems. Integrated Accessory Capability The ST5 FN was designed so important racing accessories can be added without creating unnecessary cables, hoses, or components hanging around the driver's helmet. Compatible with Stilo FN communication systems Compatible with Stilo top forced-air systems Compatible with helmet eject systems Compatible with hydration systems Available aero accessories for open-cockpit applications Compatible with Stilo ABP-specific visors Communications, forced-air components, hydration equipment, and other optional accessories are sold separately unless specifically included with the selected configuration. Factory-Installed HANS Posts The Stilo ST5 FN 8860-2018 ABP comes with factory-installed HANS posts, making it ready for use with compatible head-and-neck restraint systems. Factory installation provides a clean, properly positioned attachment solution without requiring the racer to install restraint anchors separately. ST5 ABP Visor System The ABP helmet uses a specialized reduced-height eyeport and visor designed specifically around the Advanced Ballistic Protection requirements. Stilo's center visor locking system allows the shield to be opened and closed easily, even while wearing racing gloves. Tear-off posts allow the helmet to be configured for racing environments where debris and contamination can quickly affect visibility. Important: Because of the different eyeport design, always verify that replacement shields and accessories are specifically compatible with the ST5 ABP helmet. Improved Interior Comfort Stilo redesigned the ST5 interior with more contoured cheek pads and padding designed to improve comfort and helmet stability. Removable earmuff cushions help isolate the driver's ears from surrounding noise, creating a quieter environment and providing dedicated space for compatible communications equipment. Eight-Point Top Ventilation Eight ventilation openings across the top of the helmet help manage airflow and can also be used with the optional Stilo ST5 Top Air System. A forced-air system can be especially valuable in endurance racing, enclosed cockpits, and hot-weather competition where maintaining driver comfort and concentration becomes increasingly important. Stilo ST5 FN 8860-2018 ABP Features FIA 8860-2018 ABP certified Advanced Ballistic Protection 100% medium-tensile carbon-fiber construction Ultra-lightweight FN Formula Naked design Designed for open-wheel, prototype, endurance, and professional racing Reduced-height ABP eyeport for increased frontal protection Clear ABP visor included Tear-off compatible visor system Center visor locking mechanism Factory-installed HANS posts Eight top ventilation openings Compatible with Stilo top forced-air systems Compatible with FN communication systems Compatible with hydration systems Compatible with helmet eject systems Contoured cheek pads Removable earmuff cushions Nomex interior Double D-ring chin strap Two-shell construction for optimized fit and weight Stilo ST5 FN 8860-2018 ABP Helmet Sizing Chart Stilo ST5 full-face helmets use two different shell sizes to provide a better-fitting helmet without adding unnecessary padding and weight. Competition Motorsport Fit Note: We have found that customers who normally wear a size 59 in some other helmet brands are often more comfortable moving to a Stilo size 60. Stilo helmets tend to fit slightly snugger than many competing brands, so accurate measurement is important. How to Measure for a Stilo Helmet Use a flexible cloth measuring tape and measure around the widest part of your head. Position the tape approximately one inch above your eyebrows, run it above your ears, and continue around the widest portion at the back of your head. Take the measurement two or three times and use the largest number. A properly fitted racing helmet should fit firmly and evenly around your head without creating painful pressure points.

Ultra-Light Carbon Construction for Serious Racers The Stilo ST5 FN ZERO 8860-2018 is designed to be one of the lightest carbon fiber racing helmets in the ST5 range. The FN, or Formula Naked, layout removes the integrated side ports found on the Stilo ST5 GT ZERO 8860-2018 Carbon Helmet, giving it a cleaner, more streamlined shell while still allowing compatibility with select electronics, top forced air, and helmet eject system setups. Stilo’s integrated mounting and routing design helps keep add-on systems tidy and low-profile. When those accessories are not installed, the helmet retains a smooth, uncluttered shape with nothing protruding or hanging into the cockpit. Increased Visibility Is Increased Safety The Stilo ST5 FN ZERO 8860-2018 features a taller, lower-positioned eyeport designed to improve outward visibility without compromising protection. That expanded field of view is especially valuable in fast-paced race environments where better sightlines can help the driver stay more aware of traffic, apexes, and track conditions. Each ST5 visor uses a center pinch-clip design that makes opening and closing the shield easier, even while wearing Nomex racing gloves.

Stilo ST5 FN ZERO Ultra 8860-2018 ABP Carbon Helmet The Stilo ST5 FN ZERO Ultra 8860-2018 ABP Carbon Helmet is engineered for drivers who demand an exceptionally lightweight helmet without sacrificing the highest levels of motorsport protection. Developed with input from Formula 1 driver Valtteri Bottas, the ST5 FN ZERO Ultra combines Stilo's ultra-light carbon fiber construction with the enhanced protection required by the FIA 8860-2018 ABP homologation standard. FIA 8860 certification is valid through 2032 on these ST5 FN ZERO ABP helmets. Every aspect of the ZERO Ultra has been optimized to reduce weight, from its advanced carbon shell construction to its expanded ventilation system. The result is a professional-level racing helmet built for drivers who want maximum protection, excellent airflow, outstanding visibility, and minimal helmet weight. FIA 8860-2018 ABP Protection The ST5 FN ZERO Ultra meets the demanding FIA 8860-2018 ABP certification standard. ABP, or Advanced Ballistic Protection, adds reinforced protection around the forehead area above the visor opening to help protect the driver from debris and other potential intrusion hazards. ABP helmets also use a visor opening that is approximately 10mm lower and narrower than comparable non-ABP designs. This additional protection makes the ST5 FN ZERO Ultra especially well suited for professional and high-level open-cockpit motorsport. Ultra-Light Carbon Fiber Construction Stilo's ZERO construction is designed around one goal: removing unnecessary weight while maintaining the structural performance required by FIA 8860-2018 ABP certification. The lightweight carbon fiber shell reduces the load placed on the driver's head and neck during long sessions, high-G corners, and demanding endurance events. The small shell weighs approximately 1.9 lbs and is used through size Large / 59cm. Eight-Port Ventilation System The ST5 FN ZERO Ultra incorporates eight ventilation openings across the top of the helmet to increase airflow around the driver's head. These ventilation ports can also be used with a compatible Stilo ST5 top-air system, allowing racers to add forced-air cooling for enclosed race cars and demanding cockpit environments. FN Design for a Clean, Lightweight Helmet Unlike Stilo's ST5 GT models, the ST5 FN ZERO Ultra does not incorporate communication or hydration ports into the sides of the helmet. This creates an exceptionally clean shell design focused on minimum weight and maximum performance. The helmet can still accommodate equipment such as a top forced-air system and helmet removal system. Stilo incorporates provisions for these systems during manufacturing so they can be added without bulky external components interfering with the driver's cockpit environment. Optimized Visibility The ST5 FN ZERO Ultra uses Stilo's carefully designed eye port to provide excellent forward and peripheral visibility while maintaining the additional forehead protection required for ABP homologation. Stilo's center pinch-clip visor locking system allows the shield to be opened and closed quickly and securely, even while wearing racing gloves. HANS and FHR Ready The Stilo ST5 FN ZERO Ultra includes HANS post anchors, making the helmet ready for use with compatible Head and Neck Restraint systems. The factory-installed anchor system eliminates the need to purchase and install separate posts before using the helmet with an approved FHR device. Improved Cheek Pad Comfort Redesigned cheek pads provide a more contoured fit than earlier Stilo helmet designs. The updated shape improves support around the driver's face while maintaining the comfort required for long track sessions and endurance racing. Compatible With Stilo ST5 Shields All Stilo ST5 helmet shields are compatible with the ST5 FN ZERO Ultra, giving drivers the ability to configure the helmet with clear, tinted, mirrored, and other compatible visor options depending on track conditions and personal preference.

Drivers who require integrated side ports for communications or hydration may prefer the ST5 GT ZERO, while drivers focused on minimum weight and a streamlined shell may prefer the FN ZERO Ultra. Looking for increased visibility? The Stilo Helmets ST5 FN ZERO 8860-2018 has a taller, lower-set eye port, giving you better visibility while not compromising safety. Stilo Shields use a center pinch-clip to make opening and closing easy, even while wearing Nomex racing gloves.
