Stilo's ST5 FN series of helmets eliminates the integrated accessory ports that are commonly seen on Stilo helmets. Removing these ports, and combining with a full Carbon shell, results in one of the lightest full-face helmets on the market at just 2.58 pounds for the Smaller-shell sizes. Taller eyeport is ideal for use in both closed and open cockpit racers. Snell SA2020 and FIA-8859 homologated.

Actually Measuring Your Head

Use a soft measuring tape (craft store, like $3). Wrap it around the widest part of your dome, forehead to back, and get the same number twice. Use that number to pick your size. Revolutionary, we know. lol.
