On the tall tee production website they have 4 main sizes 96 102 108 and then a TEAM. I figured out that 96 cm is like 37 inches but on the level 1 website on the tall tee production shirt is says that the 96cm is 31 (they say its equivilant to an xl on thier shirts) and thats a huge difference. Maybe the sizing is just wierd or something but I was wondring which size is actually like 37 inches on the Tall T productions Store.
