Who are Thompson Tees for?

Thompson Tees are for everyone! Whether you have a medical condition and are looking for a natural alternative for excessive sweating or need a nervousness barrier, we've got you covered! No more sweat stains means confidence and comfort every day.

Original Fit vs Slim Fit: Which one is right for me?

Slim Fit shirts are made with rayon from bamboo and are intended to fit snug, so they’re more discreet underneath your clothing. Original Fit is made from 100% cotton & provides a little more breathing room for those who prefer a looser undershirt.

How is the Thompson Tee different from other "sweat proof" shirts?

The Thompson Tee is the original sweat proof undershirt. It's the only undershirt backed by a patent from the U.S. Patent Office for our Hydro-Shield sweatproof technology, which completely absorbs & blocks sweat with breathability.

Is the underarm barrier really sweat proof?

The Thompson Tee is the only patented proprietary design that uses a clinical-grade sweatproof material that completely blocks moisture from passing through. So you can be sure that the shirt won't lose its effectiveness over time, wash after wash.

What's the story behind the Thompson Tee?

Spurred by their struggles with hyperhidrosis, a medical condition causing heavy perspiration, friends Billy Thompson & Randy Choi, joined forces to create the Thompson Tee, a sweatproof tshirt solution to the embarrassing sweat marks and stains.
