I bought this hoodie for my boyfriend (secretly for me though) and he wears it so much I haven't had a chance to yet! It's the first thing he puts on when he gets home from work (and he's one that has his go-to's and wears nothing else). For reference, he's 6'2" and muscular in the arms and shoulders, and the L fits perfectly & with enough room for full arm and shoulder movement without it being too baggy looking.
