 The Stilo Helmet ST5 GT 8860-2018 carbon helmet was designed for professional racers needing to satisfy the strictest FIA 8860-2018 regulations.  It is also the helmet of choice for drivers who won’t compromise their safety, no matter what or where they’re racing. This certification provides an unparalleled level of puncture protection as well as impact resistance.
 A Premium Racing Helmet that is Ultralight and Adaptable 
 The Stilo Helmet ST5 GT 8860-2018 is among the lightest carbon fiber racing helmets on the market. With its two integrated side ports, it can be outfitted with any combination of electronics, side- or top-forced air, hydration, and a helmet eject system. Thanks to Stilo's innovative design which incorporates mounting and routing for these options at the time of manufacture, integration is sleek and seamless. When not in use, you don't even know these features are there.
 Looking for increased visibility? The Stilo ST5 GT 8860-2018 has a taller and lower eyeport, giving you better visibility while not compromising your safety. Each visor has a center pinch-clip to make opening and closing easy, even while wearing nomex racing gloves.
 
 At Competition Motorsport, we've found that customers who typically wear a size 59 in other helmet brands are most comfortable in a Stilo size 60, which uses the large shell. Please order accordingly.

 Measuring Your Head 
 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 then around to the front again. It's a good idea to take two or three measurements to make sure you have the largest one.
