I am 5' 9" tall, 160 pounds and average build. I purchased the Carhartt and Wrangler Riggs work shirts in size large, to allow for dryer shrinkage.

Overall, the Riggs shirts come out of the dryer ready to wear and have a nice, soft feel. The Carhartts come out of the dryer wrinkled, especially the collar and seemed to shrink a bit more, which I can feel with a slight restriction of my upper body movements.

The ONLY advantages my Carhartts over the Riggs is the long sleeved variant has more room in the forearm area, where the Riggs is a bit snug, and they have a much larger color selection.

Overall the Riggs seems to be a noticeably better shirt.
