“My husband is 6'1", wears a 16-1/2 x 34/35 dress shirt and a 36/33 in pants. I keep seeing reviews saying that this coat runs small, and I'm not sure how much to size up. He has a dressy trenchcoat that's a 42L and several Woolrich coats in L and XLs, depending on individual coat fits. I'm leaning toward an XL, but do you think I need a 2XL?”
They make a tall version which I would recommend. At his height and weight he is thin-I would go with large tall.
