There were a few of my Florida brethren on here this summer talking about a kind of shirt that drew the sweat away from the body and kept them dry despite the humidity. With the colder weather coming and snow work right around the corner, I'm interested in finding some of these shirts. Anyone know what these are called, where I can find them? Being drenched with sweat while working in 20 degree temps isn't the most ideal conditions for good health. Thanks in advance.
