Men’s Sweat Proof Undershirts

Thompson Tees are for everyone looking to keep sweat off shirts and sight! Regardless of your age and whether you're dealing with hyperhidrosis or just want a little extra protection against nervous sweat, our sweat proof undershirts have got you covered. They are a comfortable, effective, chemical-free solution to underarm sweat marks.

Choosing between the Original Fit and Slim Fit depends on your personal style and comfort preference. The Slim Fit, made from a blend of bamboo rayon and spandex, offers a snug fit that stays discreet under clothing, ideal for those who prefer a streamlined look. The Original Fit, crafted from 100% cotton, provides a more relaxed fit, offering extra room and breathability, perfect for individuals who appreciate a classic, looser undershirt feel.

Thompson Tee was born from the personal journeys of friends Billy Thompson and Randy Choi, both of whom experienced the challenges of hyperhidrosis, a condition causing excessive sweating.
