Versatile, comfortable, and biodegradable -- yay!
I live in an area with a lot of warm weather and it's great in the heat and as a layer when it gets cool. Can be dressed up a bit or just very functional with tasteful finish that makes it just that important bit more than a plain old tank. Soft and flattering.
I've managed to get a pen mark on it and some early sweat stains: both were easily removed with a mixture of dish soap, baking soda and hydrogen peroxide.
