Stilo's ST5 FN series of helmets eliminates the integrated accessory ports that are commonly seen on Stilo helmets. Compared to the classic ST4 helmet, the ST5 GT features a taller eyeport to allow for use in both closed and open cockpit racers. The lightweight fiberglass shell is manufactured in two shell sizes (one for X-Small through Medium, and another for the larger sizes) allowing for weight savings without sacrificing fit.
