The Original Sweat Proof Undershirt
Don't be fooled by other imitation shirts! We poured years of hard work (and lots of armpit sweat) into perfecting our sweatproof shirt, the only sweat proof undershirt to earn a U.S. patent for our Hydro-Shield sweat proof technology. Our integrated sweat proof underarm sweat pads are complete with anti-microbial and hypoallergenic properties, without the use of chemical treatments so the Thompson Tee will not lose effectiveness over time!
