fits perfect...seems well made

I ordered this shirt for my husband, who wasn't too psyched about it to begin. The size runs too small.  He is a large.  We ordered a medium, as per the sizing guidelines.  My husband is neither overweight nor husky.  He's pretty fit and a runner.  Yet, he's a full sized large.   Upon receipt, he was pleasantly surprised to find that he LIKED the color and quality of the shirt but it was too small.  He's happy enough with the shirt, that I'm exchanging it for a large.  My recommendation is order one size up if you're a full size .
