WOMEN'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.

Our sweat proof undershirts feature proprietary layering and stitching techniques that work like reverse osmosis. This means they draw sweat away from your skin and release it as vapor, preventing sweat from reaching your outer clothing, and keeping you dry throughout the day.

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. Motivated by a desire to offer a solution to the embarrassing issue of sweat marks and stains, they created the Thompson Tee—a revolutionary sweat-proof undershirt that transforms confidence in everyday life.
