Thompson Tee Sweat Proof Undershirt


Thompson Tee’s undershirts for men and women have patented, sweatproof technology, have no chemical treatments, are proudly made in the U.S.A. and are machine washer and dryer safe. Thompson Tees are perfect to wear while traveling, at work, working out, outdoors and more. More than one million of these have been sold, and they are available in a variety of styles, colors and fits.

Thompson Tee is also doing their part to manufacture face masks and donate to hospitals and healthcare workers in need. The masks are reusable, washable and are made with premium breathable, soft cotton and fit the CDC cloth mask recommendations. Thompson Tee has exceeded their goal to donate 15,000 masks to hospitals in need; today, they have donated 30,000 face masks and counting.

Founders, Billy Thompson and Randy Choi, were featured on Shark Tank in 2018.

Thompson Tee is made in the USA. Founder, Billy Thompson, also an Asian-America, is a sufferer of hyperhidrosis and learned to live with this condition – practicing ridiculous deodorant rituals, swearing off colored shirts and doing everything imaginable to conceal his underarm sweat marks. After scouring the market for a comfortable and effective sweat proof undershirt, he found nothing, so together with his business partner, Randy Choi, they spent more than 10 years developing a lightweight, breathable, comfortable and truly integrated underarm barrier that completely absorbs sweat and withstands the toughest stains.
