I'm sure it's been asked countless times, but I own a few Reebok Premier replica jerseys from 2013-15 and they are size Small (S) and fit me great. Not a ton of room but I like less bulk. I'm looking at some CCM 'Vintage Hockey' jerseys and they also go by Small, Medium, Large etc. in sizing and not by number (like 48, 50 etc.) My question is: how do they compare to the Premier jerseys? Is it 1:1 or would a CCM Vintage Medium fit like a Reebok Premier Small? Thanks in advance.
