Thompson Tee create sweat proof and premium undershirts that block 100% of underarm sweat and odour with patented Hydro-Shield sweatproof technology. Billy had axillary hyperhidrosis (excessive underarm sweating) and would practice ridiculous deodorant rituals to conceal his underarm sweat marks. In 2011, he approached friend Randy Choi, who had experience working in the apparel industry. Billy learned that he too, could relate to the struggles of excessive sweating. Randy, who suffered from cranial hyperhidrosis as a teen, underwent sweat gland removal surgery, only to end up with severe side effects which included all-over sweating, skin problems, slow metabolism and fatigue as a result. Bound by a shared passion to create a safe, affordable and convenient solution, they both developed a lightweight, breathable, comfortable and truly integrated underarm barrier that would completely absorb sweat, withstand the toughest stains, and help those living with axillary hyperhidrosis.

In a recent episode of the MenswearStyle Podcast we interviewed Billy Thompson, Founder of Thompson Tee about axillary hyperhidrosis and the founding story of his brand which has sold over million shirts in 10 years. Our host Peter Brooker and Billy talked about undershirt trends in the US vs UK, bootstrapping, production, Shark Tank, patented sweatproof technology, how to combat copycat businesses, and being featured on TV.

“Our undershirts are designed for people who suffer from a condition called axillary hyperhidrosis, which is excessive underarm sweat. And then they’re also for those people who sweat on a situational basis, whether it be a meeting or a job interview. They will also protect your expensive custom-made dress shirts from damage such as pit stains and antiperspirant stains.”
