Stilo ST5.1 GT: Still #1 With Integrated Flexibility

The Stilo ST5.1 GT Composite is Stilo's Snell SA2020 version of their best-selling kevlar-carbon composite helmet. With an autoclave molded shell, the Stilo ST5.1 GT Composite auto racing helmet offers superior safety and protection compared to fiberglass and composites of competitors helmets. You get all this without sacrificing comfort or features, as Stilo continues to focus on minimizing weight and maximizing flexibility.

With its large eye port, the Stilo ST5.1 GT Composite offers unsurpassed peripheral vision and all of the available tinted, mirrored, and iridium-colored visors (sold separately) have a center pinch-clip to make opening and closing easy, even while wearing nomex racing gloves.

Although updated to meet the newest Snell SA2020 certification, the Stilo ST5.1 GT retains its FIA 8858-2015 homologation as well. This makes the helmet legal in nearly all road-racing competition (some sanctioning bodies do require FIA 8860 homologated helmets.)

The Ultimate Auto Racing Helmet Buyers Guide

Stilo ST5.1 GT Gives You the Ultimate in Flexibility Built In

The Stilo ST5.1 GT Composite is unsurpased in built-in flexibility. Its two side ports can be fitted with 3 different types of integrated communication electronics, forced air, helmet eject system, or a hydration system. Thanks to its innovative shell design, mounting and routing these options to the Stilo ST5.1 GT is sleek and seamless. When not in use, you don't even know the features are there.

Whether you're using side-mounted communications, side air, or a built-in hydration kit for staying hydrated during long enduro stints, everything is neat, tidy and completely out of the way when not needed. Stilo offers simply the best modular racing helmet on the market.

Industry-standard M6 threaded receivers are molded into the helmet shell to accommodate anchors for whichever head-and-neck restraint you use.

Note: We have found that customers who typically wear a size 59 in other brands are most comfortable in a Stilo size 60, which uses the large shell. Please order accordingly.

A Note About Helmet Sizing and Head Measurement

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.
