My 6 year old wears a S/M. I bought it for about 40. not sure if they raised the prices or not. Its not numbered. Its a little big but they are supposed to be big.
hmm, not according to RBK. (tight, form fitting jerseys - you'll just FLY across the ice!!)
and make sure and get the fight strap for your kid's jersey. Anything less, is.. well... less.
