HanesBrands men's tanks used to be made to last, but something has changed. The fit was way off and the quality has suffered too. My husband normally wears a large, but the larges fit me like a glove and I'm a 5'3 140lb woman. He had to go up to a 2XL. His larges from several years ago fit just fine and he hasn't gone up sizes otherwise. Definitely size up one or two sizes if you buy these and expect to replace them much sooner than you used to have to.
