The Thompson Tee Difference
Do you struggle with managing excessive armpit sweat? You’re not alone.
Thompson Tee provides a practical, comfortable solution for those who deal with excessive sweating or hyperhidrosis. Our sweat proof undershirts help eliminate embarrassing sweat marks and yellow stains while improving your confidence and quality of life.
Patented Sweat Proof Technology
Our lightweight layering system traps heat and moisture and allows them to evaporate – meaning wet marks, sweat stains and odor won’t seep through your clothes.
Highest Quality Materials
All our products are designed in America. We source raw materials from the U.S. exclusively, partnering with American and global facilities that commit to the highest fair labor and environmentally-friendly standards.

Machine Washable
Wash your Thompson Tees as often as you like. Our sweat proof technology won’t wear out over time.
Tag-Free
All sweat proof undershirts are designed with tagless, lay-flat collars, so there’s no irritation, itching or bulk.
