Longer corresponds to a 38 to a 36, but preferring to wear hoodies a size up, this is not a concern. Very nice product, very hot also. However, the red of the picture is much brighter than that of the product received. The sweater that I had a red that pulls burgundy red / dark, making it a bit dull. Warning color level not quite so consistent! Seller very responsive in trade (by email anyway). In short, thrilled, I recommend!
