LONG, TUCKABLE LENGTH THAT STAYS PUT

Move through your day freely. The women’s scoop neck undershirt is designed with extra length to stay tucked in all day. So go ahead and wave those arms around!

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.

The shirt and size you choose will ultimately depend on your fit and style preferences.

Both our Men’s and Women’s Slim Fit shirts are made with rayon from bamboo and are intended to fit snug, so they’re more discreet underneath your clothing.

The Original Fit is made from 100% premium combed cotton and provides a little more breathing room for those who prefer a looser undershirt. If you're looking for the most sweat protection but like the fit of a typical T-shirt, you may want to try a size up in the Original Fit shirts.

Either way, both options come with our proprietary Hydro-Shield Sweat Proof Technology, backed by our Sweat Proof Guarantee!

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!

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.
