Hydro-Shield®: The Only Patented Sweat Proof Technology

Stop wasting time on solutions that stink. Try a sweat proof Thompson Tee with patented Hydro-Shield® sweat proof technology and block 100% of sweat stains instead!

Hydro-Shield®: The Thompson Tee Difference

Thompson Tee stands apart from other "sweat-resistant" and "moisture-wicking" shirts by absorbing and evaporating sweat rather than simply transferring it to other parts of your body.

  • Hydro-Shield®, our patented, clinical-grade sweat proof material, was designed to completely block sweat from showing through your outer layers.

  • Thompson Tee’s proprietary layering and stitching uses reverse osmosis to pull sweat away from your skin. Sweat then escapes as vapor, leaving you feeling cool and dry – no embarrassing wet marks!

  • Thompson Tees are made from 100% premium combed cotton. Hydro-Shield® pads are fully integrated into the overall shirt design and never need adjusting. All of our shirts can be machine washed and dried like any normal undershirt.

Hydro-Shield® Patented Technology

Thompson Tee is the original sweat proof undershirt. We earned a patent from the U.S. Patent and Trademark Office for our Hydro-Shield® sweat proof technology in 2014. Although competitors might say their shirts are "sweat proof," no undershirt is designed to protect you like a Thompson Tee, and no other shirt has patented technology to back up that claim.

Others use chemically treated material that washes out over time. However, Hydro-Shield®’s native properties are part of the fabric, maintaining its effectiveness wash after wash. In addition, our specialized textile process does not contain or emit any volatile organic compounds (VOCs)

Great for Sensitive Skin

Thompson Tees are suitable for sensitive skin for several reasons:

  • Breathable materials: Thompson Tees are made from soft, breathable fabrics like bamboo and cotton which allow air to circulate, reducing sweat-related skin irritation.
  • Hypoallergenic: The natural materials used in Thompson Tees are less likely to cause an allergic reaction in people with delicate skin types.
  • Chemical-free: Sensitive to chemicals? Thompson Tees are free from harsh chemicals like bleach or formaldehyde, which can cause reactions on easily irritated skin.
  • Tag-free: Clothing tags can be a real pain, especially for those with tender skin. Thompson Tees do not have tags or labels that can rub against you, ensuring maximum comfort.
