MANLUODANNIMen's Winter Black Warm Jacket Hooded Outwear Coat (M, Black)

I'm a 44 inch chest with long arms. Roughly 50 inch shoulders. I wonder if you could translate your sizes to that appropriate size to fit me ?

Is it warm enough to wear in a snow day？

I want to cancel the order

My son's a 42inch chest normally wears medium, which size shouldi order? Would I get this before Christmas
