"Item is cool. I'm 6 foot, 195 lbs and the jacket is a little tight on me! I maxed out at the 3XL (XXXL). If your around my size I would do the same. I have really long arms as well. The jacket is pretty good quality. Also it is warm. Seller was cool and shipped item promptly. Only thing I feel seller should do it post the sizes measurements for each S M L XL etc."
