I have 3 boys, all big - 2, 3, and 4X. All are over 6 feet tall and have big chests. Finding clothes for them is a problem. All lift weights and have big arms. All work outside in the cold and heat. Cotton is their fabric of choice. But finding quality clothes construction in sizes like this and at prices we can afford presents a problem. These were just right and I will be ordering more if they are available.
