I'm a tall guy, about 5ft 10 inches and 400 pounds. It's very difficult to find comfortable clothes at a reasonable price for my height. This shirt fits my size. I play in the pool league and this shirt has helped me stay cooler and drier than anything I've worn before. It's comfortable, doesn't pinch and has ventilation that helps keep me dry in the Arizona summer. I definitely recommend this shirt. The only improvement would be to have the same shirt with a front pocket.
