The Stilo ST5 FN Carbon Zero helmet is a lightest in class iconic helmet used in a variety of race types. Crafted from a high-tensile carbon fiber layup and exceeding the FIA 8860 rating, this helmet is designed for top performance. Predominantly used in open cockpit environments and features an array of improvements from the ST4 Helmet Weighing in at 2.58lbs in the small shell size and 3.15lbs in the large this helmet not only looks good but will minimize neck and head strain. The ST5 FN Zero helmet was designed for top level racing where every ounce matters. The FN (Formula Naked) helmet line was designed for open cockpit environments and features an aerodynamic design, while still offering an array of features making it the go-to helmet for racing professionals. The ST5 builds upon our ST4 design with a larger eye port which opens past the line of sight and includes an 3mm clear visor coming standard with our anti-fog coating. Improvements also have been made to the interior design with removable cheek & top pads allowing drivers to obtain the perfect fit. Helmets come standard with removable earmuff cushions which provide a significantly quieter environment for the driver by isolating the ear. Other Features: All Stilo closed faced helmets come in two separate shell sizes allowing us to craft a better fitting helmet that is lighter weight. Ready for non-integrated electronics, air supply, and hydration or any combination of the three this helmet is one of the top helmets on the IMSA grid.
