I wanted a new XC shirt. I run hot so don't need heavy wt. Got the XXL and it fits nicely around the stomach. Wish the Zipper was 3 inches longer for venting but I like the high neckline and long sleeves. Would be nice to have thumbholes but the material is so soft. I'm 5'8" and wear either XL or 1X. KariTra trends to run small.
