Why do men wear tank top undershirts?

Question

I have a large selection of undershirts, v-necks, white, black, and crewnecks. Recently, I thought I would purchase some of the tank top undershirts and I am wondering what the purpose of them is. I bought some, but I can't figure out what they are for. Regular undershirts protect your outer shirts from sweat marks. What are the tanks for...if you sweat, it goes right on to the outer shirt?

Answer 1

Tank top undershirts are great.  They are the most comfortable, keep you warm in Winter and cool in Summer, and my girl thinks they look s**y.  That is good enough for me!

Answer 2

Tank top undershirts are extremely comfortable, and they keep your body cool.

Answer 3

I wear them for the comfort and because they are not as confining as a t-shirt. They do absorb sweat and, if fitted properly, provide some underarm protection. Fortunately, I do not sweat profusely under the arms. Plus, I prefer the look of a tank top undershirt as compared to a t-shirt.
