If I remember CCM/Maska sizing in the 90s is a lot different
Authentic sizing was 44, 48, 52, 54, 56, 58 (size 54, 58 I think were only available from the stores that were doing the jerseys for the team)
I think determining sizes went like this: measure length armpit to armpit and double it to get the size i.e 22" across is a size 44
Remember that players usually wore equipment underneath and back then, equipment was a lot smaller i.e shoulder pads, elbow pads
I think when equipment started getting bigger around the mid 90s to now, that jerseys kept the sizing numbers but the actual sizes became bigger. Wasn't Starter jerseys the ones that started getting way bigger than CCMs before them?
I know that beginning with Starter, size 44 was dropped and size 60 was introduced.
I believe all the other companies following Starter (ProPlayer, CCM/Koho/Reebok) just kept the sizing of the jerseys.
I do not have enough experience with RBK Edge/Edge 1.0/Edge 2.0 jerseys for sizing because the jerseys became "streamlined" and then changed back to bigger sizes when players complained. I have seen Edge 2.0 Size 58+ and maybe Size 60+ but i do not know if that mean bigger arms or chest size.
