Faqs about our tees

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 and Trademark Office for our Hydro-Shield sweat proof technology, which completely absorbs and blocks sweat while maintaining breathability. Although others might say "sweat proof," no undershirt can protect you like the proven Thompson Tee, and no other shirt has patented technology to back up such a claim.

Here are a few of the features that make our sweat proof undershirts unique:

  • Proprietary layering and stitching system blocks sweat from seeping through your underarms.
  • Sweat proof technology won’t wash out or lose effectiveness over time.
  • Separate front and back panels to trap sweat effectively, minimize heat build-up and keep you feeling cool.
  • The underarm barriers are created with a center seam design for a sleek, smooth fit that doesn’t bunch under your clothing.
Is the underarm barrier really sweat proof?

YES - We didn't just call it "sweat proof." We earned it! The Thompson Tee is the only patented proprietary design that uses a clinical-grade sweat proof material that completely blocks moisture from passing through. Other shirts may advertise "sweat proof" but don’t hold moisture well. They typically consist of two cotton layers and are often treated with chemicals that could wash out over time. The benefits of our sweat proof technology are native properties, so the shirt will not lose its effectiveness over time. That's why every Thompson Tee with Hydro-Shield Sweat Proof Technology comes with a Sweat Proof Guarantee. We guarantee that your underarm sweat won’t penetrate the sweat proof barrier — or your money back!

How does the sweat proof underarm barrier compare to sweat pads?

While armpit pads and sweat shields may absorb some sweat, they do not allow moisture to evaporate. So throughout the day, armpit pads can lose their stickiness due to sweat or become heavy and bulky beneath your shirt.

Unlike sweat shields, garment guards and sweat pads, Thompson Tee's sweat proof barrier is the only patented sweat proof technology available. By trapping sweat and releasing it through evaporation, your sweat won't show through your outerwear. Plus, you won't have to worry about adjusting your sweat pad or changing it out for a new one throughout the day.
