The product fits perfectly and is flawless apart from protruding threads and surface damage. The only problem is that this product is suitable for people with shark fins or humpback whales. There is a cartoonish excess of fabric along the waist that flaps backwards like a parachute. It's hard to put in because of the aforementioned back pocket, and if I had an odd medical condition that causes a beer belly but on my back, this shirt would fit me perfectly.
