Frequently Asked Questions
Who are Thompson Tees for?
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.
Original Fit vs Slim Fit: Which one is right for me?
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.

How is the Thompson Tee different from other "sweat proof" shirts?
Thompson Tee stands out as the pioneer in sweat-proof technology, being the only undershirt patented in the U.S. for its Hydro-Shield sweat proof design. This cutting-edge technology not only completely absorbs and blocks sweat from showing but does so while maintaining breathability, a unique balance that sets us apart from other alternatives.
See how Thompson Tee stacks up against other alternatives.
Is the underarm barrier really sweat proof?
Yes, the underarm barrier in Thompson Tee uses a patented, clinical-grade sweat proof material, ensuring that moisture does not penetrate the fabric. The innovative design maintains its effectiveness over time, wash after wash, providing reliable, long-term sweat protection.
If it doesn't absorb sweat, where does the sweat go?
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.
What's the story behind the Thompson Tee?
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.

Aside from underarms, does the shirt prevent chest and back sweat from showing?
Thompson Tee is specifically designed to target underarm sweat. While it offers some general moisture-wicking properties for other areas like the chest and back, its primary focus is ensuring complete protection for the underarm area.
Does it stop working after a couple of washes or after a few times?
No, Thompson Tee is engineered for longevity. The sweat proof barrier retains its effectiveness through numerous washes, offering reliable sweat protection over repeated use. By following our care instructions, you can ensure your tee continues performing optimally for a long time.
Our customers report that their tees last several months to over a year with proper care.
