I ordered the Largest size since I'm 6'1 and didn't want to take a chance with anything smaller than the largest they had. When it arrived and I put it on I was glad I made this choice. The sleeves like everyone else says are indeed tight but that's the design of slim fashion which kinda bothers me, hopefully I can get use to it. But even with that being the case I still give this a 5 star, the feel it comfortable and wouldn't make you feel hot when it's not cold. But if it's really cold you might want to get something else because air goes straight through this hoodie.
