There’s nothing more disgusting than pit stains on a hot summer day.

What if we told you we found the easy closet solution to no more pit stains — ever? Thompson Tee is a patented undershirt brand that’s guaranteed to block underarm sweat for both men and women.

Founder Billy Thompson and his partner Randy Choi — who both suffered from a chronic condition that causes excessive sweating — built the brand to combat the stigma around pit sweat. Not only do these shirts stop sweat, they also eliminate odor.

The Women’s Sweat Proof Undershirt is available in three colors and offers a slim fit, making this an everyday essential whether you’re headed to work or to happy hour. Wear it under an outfit, or by itself it makes for a cool, dry look. It’s made from a rayon-spandex blend, and the best part? The sweat-proof features don’t fade over time, even with consistent washing. The material is lightweight, too, so it won’t feel heavy on your skin, even in the hot summer heat. Sizes run from XS to 2XL.

The men’s undershirt is also a bestseller and offers the same sweat-wicking technology the brand is known for. It’s available in seven colors and sizes ranging from XS to 3XL. This option is also made of ultra-soft cotton, built for all-day wear, whether you’re out in the field or relaxing indoors.

Each shirt, according to the brand, is built to last years, and the brand even sells sets if you’re looking to stock up on a few. Shop these sweat-proof undershirts now and save your wardrobe this summer.
