I first found these Fruit of the Loom at a K-Mart over ten years ago.  I live mostly in the tropics and like the comfort of cotton.  This style is very comfortable and I wear it for work and home year round.  I have several now.  They are easy to get on and off.  I don't like racer backs...this style goes about four inches up in the back and does not pinch anywhere.  I was so happy to find these through Amazon after many years of looking in stores and not finding them.
