"Great lightweight shirt with a minor flaw"
I just ordered my third GTD shirt. This shirt does an excellent job of wicking away sweat and moving air to the body. Very light weitght. I'm 6'2", 190 pounds and wear a large in this TNF style and it's not too tight. An XL for me was too roomy and baggy. While this material is very light weight and airy, its flaw is that the shirt is subject to snagging. It will snag if running through the woods and a branch hits the shirt. Some people don't like snags, I'lltake them if the shirt can move air and sweat as well as this one does.
