first regarding pro-tec
1) are the BMX and skateboarding helmets the same?

2) B2 helmets are S, M, L, XL while ace are Jr/M, M/L, L/XL. i believe i tried on an ace L/XL and it was too small. would a B2 XL be bigger? the shops around here are lacking and the staff is mostly the winter ski staff (not many bike only shops).


finally, what other brands should i look into? if you can't tell, i have a large head(measured 23.5" roughly), so preferably a company that offers big sizes.
