The Thompson Tee Difference
Patented Sweat Proof Technology
Our sweat-proof shield design allows sweat to escape as vapor, meaning sweat, yellow stains and odor won’t seep through your clothes.
Highest Quality Materials
All our products are designed in America, and we only source raw materials from the U.S. We partner with American and global facilities and 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.
No Tag
All our shirts are designed with tagless, lay flat collars - no itching or bunching up.
