If I found a helmet for my macro encephalitic gourd , then you can too.
If not , then maybe you should consider work as a parade float or inflatable for Macy's Thanksgiving day parade.
Best advice here is to go out and try some on though.............they are not all created equal.
I have an old Bell open face that is snug and an I forget who's closed face that fits live a glove.
O.K. , a one fingered glove .......... but it fits.
