1. THOMPSON TEE

When looking for the best sweat proof undershirt, you want to make sure it works.

Thompson Tee is the only patented sweat proof undershirt. Its proprietary stitching and layering system, Hydro-Shield, traps moisture and releases it as vapor, which stops sweat from seeping through.

Other sweat proof undershirts are treated with chemicals to wick away sweat, which wear off quickly, or have removable armpit pads that slide easily and produce more heat.

Thompson Tees’ sweat proof barriers are built directly into the armpits, so the sweat protection doesn’t wash out or lose effectiveness easily.

Plus, they’re made in the USA and come with a money-back guarantee, so you can feel confident when purchasing.

COMPARING SWEAT PROOF SHIRTS

Still unsure which undershirt is best for you? Here are a few critical factors to consider when putting any sweat proof shirt to the test:

  • Sweat proof technology: You want it to work. No sweat marks or pit stains, period.
  • Price: You want high quality without paying an arm and a leg.
  • Design, fit and length: Undershirts and T-shirts are wardrobe staples that should fit well and hold up to daily use and washing. If you’re wearing the garment as an undershirt, make sure it’s comfortable under your clothes and it stays hidden with different tops and necklines. It also needs to be long enough to stay tucked in.
  • Return policy or guarantee: Prioritize brands that offer flexible return policies. When it comes to sweat proof undershirts, you’ll want to wear it and wash it before deciding if it’s right for you.
