What a great shirt. I got it because it was moisture wicking. Wore it to the gym, worked out vigorously, sweat like crazy, and it worked like a charm. My wife (who sweats like a runner in a marathon.in Dubai.during August, but that's a story for another day) wore it during a hot yoga session and she walked into the house not stinking - a testament to the efficacy of this shirt if there ever was one.
