Stilo Helmets ST5 FN 8860-2018 ABP The Stilo Helmets ST5 FN 8860-2018 ABP carbon fiber helmet was designed for professional racers needing to satisfy the latest FIA 8860-2018 ABP regulation. It’s also the helmet of choice for drivers who won’t compromise their safety, no matter where they’re racing. This certification provides an unparalleled level of puncture protection as well as impact resistance. ABP is an acronym for "Advanced Ballistic Protection". The ABP replaces the zylon panel required by FIA in the previous generation (FIA 8860-2010) helmets, integrating stronger protection into the front of the helmet shell. A brand new testing procedure was introduced to evaluate this area, based on military ballistic specifications with a projectile shot at 250 km/h. The Stilo ST5 FN ABP was the first helmet to be certified to this new standard, offering a higher safety degree while maintaining dimensions and weight. The Stilo ST5 FN 8860-2018 ABP is among the lightest carbon fiber racing helmets on the market. While it lacks the side ports of the Stilo ST5 GT 8860-2018 Carbon Fiber Helmet, it can still be outfitted with electronics, top forced air, and a helmet eject system. Thanks to an innovative design incorporating mounting and routing for these options, integration is sleek and seamless with nothing protruding, hanging down, or otherwise getting in the way. When not in use, you don't even know they're there. Looking for increased visibility? The Stilo Helmets ST5 FN ZERO 8860-2018 has a taller and lower-placed eyeport, giving you better visibility while not compromising your safety. Every Stilo visor has a center pinch-clip to make opening and closing easy, even while wearing nomex racing gloves.
