I got these for my husband because he had a black E. Armani tank that he has uses as an undershirt.  We were both blown away by the softness of the black cotton tank. It occurred to me that the shirt probably comes in white, and sure enough I found it on Amazon so I decided to treat him to a 3-pack of white ones to supplement and eventually replace his time-honored Fruit-of-the-Loom undershirts. I have a feeling he will never want another brand.  They are a big hit. Highly recommend them - can be worn alone or as an undershirt.
