Hanes Men's TAGLESS® ComfortSoft® A-Shirt 7-Pack (Includes 1 Free Bonus A-Shirt)

I bought these because I was reading in an article about dressing professionally that they are great for under the buttoned up tailored jacket or Channel jacket because they eliminate draft and are not as cumbersome feeling as a full blouse. Plus at the price, once they turn gray or yellow, they are easy to replace. They are the bomb underneath work out clothes on the days that it is still a bit on the cool side.

I'm a woman, but I've used these men's shirts as undershirts for years because they're more comfortable and less obvious under clothing than women's tanks. However, this last purchase was extremely long in length -- the good news is that they didn't shrink even after washing in hot water and drying at high heat.
