They fit fine, for reference we got him an XL and he is 6'1" and skinny. They may be a smidgen long but if we had sized down the sleeves would have been short on him, as he has long limbs. Think skinny tree and that's my man, haha. They definitely help keep him warm without him feeling constricted which is great for the work he does. We'll be buying a few more pairs soon!
