I first ordered an XXL for my 5'11" boyfriend.  He wanted it in a size that could fit over a sweatshirt & found it ran a little short for his liking.  I was nervous about an XXXLT, but aside from the sleeves being a bit long (which he could care less about), the fit is GREAT!  I know he will get a lot of use out of this.  And I love the look of it!!  Win-win!
