i just measured the men's ones around the chest
M = 43 Inch(s) = 109.22 Centimetre(s)
L = 45 Inch(s) = 114.3 Centimetre(s)
XL = 48 Inch(s) = 121.92 Centimetre(s)
finally managed to get through the whole order process in the shop (thank you, google translate).
Seems to me like a kind of initation ritus for new members
Can't wait for my shirt!!!
