    Helmet Fitment

    Trust my head with it

    For years if i had a helmet on it was a novelty for riding through helmet law states. This year when the bikes came out I dropped my novelty and watched it crack apart. I told my man i was getting a real helmet. He laughed and said “your head your choice”. He does own and occasionally wear a DOT. Helmet. I had decided i wanted more than a beanie and found the biltwell 3/4 gloss black. The sizing runs dead on. I got a s and it fits perfectly. No bad wind noise and it stays sput have worn it on several multi-state rides with no complaints. It is heavier than my novelty but There is an actual helmet on my head now and not a a worthless plastic cap. Glad I bought it. ride on
