Good grief. Are you sure about the measurements?

Maybe you have a very round head. Most helmets are oval in shape.

My head is roundish at the top so helmets that are more oval/racier will not fit.

I can't fit AGV. HJC barely fits. So far Bell and Shoei has the best fit for my head. I would say Bell is the roomiest.

Also, try helmets that have 3 or more Shells across the sizes.

Otherwise you may have to stick with jet helmets.

Anyone know what to do with old helmets? If recycle, where exactly?

Or are there shops that accept old helmet trade ins?
