I actually own both. A bell Half and a scorpion full face. I'm thinking they are both same size. Both fit great, I'd find something in your price range that you like, I'd suggest at least DOT approved maybe both, (my scorpion has both). Anyway find one or a few you like read reviews, ask opinions then go to a shop and see how they feel on. Walk around the store in it to get a good feel. I mean this thing is gonna be on your head for a while I assume. Even if you plan on odering it online I'd still try one on in person.
