Size S/M pro stock Bauer 5100 for sale. I'll send the helmet with the white loops attached, as well as the set of black loops that it came with if you're into that sort of thing. I will not however send it with the visor. Sorry.
With respect to the sizing, I wear a 7 1/4 baseball cap and a medium 4500. This helmet fits me beautifully when almost fully expanded.
$75 and shipping.
