What Are the Best Undershirts for Men?

Sweating is a normal biological process.

Whether you suffer from excessive sweating or not, sweat stains on clothes are uncomfortable. You spend a lot of time worrying about whether people can see them.

Sweat stains and sweat patches are embarrassing and can affect your confidence.

Investing in undershirts that absorb sweat and keep you comfortable all day long is critical.

Modern men’s undershirt manufacturers are using different technology and techniques to produce luxurious, stylish, comfortable and absorbent t-shirts.


There are some questions to keep in mind when buying the undershirts:

  • Does the fabric have wicking properties?
  • Do they have sweat-pads that draw moisture away from your body?
  • Are they a tailored fit?
  • Are the undershirts available in different sizes and colors?

To guide you, we have compiled a list of the best undershirts for men available in the market.

Sweatshield Men's Sweat Proof Undershirt

If you’re looking for a luxurious, stylish undershirt designed to prevent sweat from showing through your clothes, then the Sweatshield Men's Sweat Proof Undershirt is the perfect undershirt for you.

Made from the silky smooth micromodal fabric, Sweatshield Men's Sweat Proof Undershirt guarantees comfort as it is 50% more absorbent, breathable and cooler than cotton.

The Sweatshield Men's Sweat Proof Undershirt stay-cool technology integrates armpit sweat pads that absorb the sweat and prevent the sweat stains from showing on your clothes.

The undershirt offers a tailored fit.

You can wear it under polo shirts, t-shirts, casual shirts and business shirts and still be comfortable. It can be worn solo too, for that casual look.

It’s tagless, making it very comfortable to wear.

The undershirts are available in both V-neck and crew neck styles and come in black, white and beige.

Sweatshield offers a 30-day exchange or refund policy.

One distinct feature sets Sweatshield undershirts apart from most options - they are designed to be sweatproof.

While regular t-shirts and undershirts may quickly start to yellow around the underarms and attain a sweat-like smell, Sweatshield undershirts keep you fresh and cool.

If you’ve found yourself sweating more than usual, you may have hyperhidrosis or diaphoresis.

One way to deal with these conditions is to wear sweat-proof clothing such as Sweatshield undershirts.

Want to find out more? Stick around. We’ll delve into that in more detail below.

For over a decade, Sweatshield has built quite a reputation for itself. The result? An entire webpage dedicated to positive feedback from customers around the world.

Here's a sample:

“Hi there. I just wanted to say how your undershirts have changed my life! I have suffered with excessive sweating for years and it has held me back in so many ways. I came across your sight and at the time you only sold men’s undershirts but I made do and they were fantastic.

I am so pleased that you now provide women’s undershirts. I have just had one delivered to check the size and have now ordered 5 more! I never would have thought something so simple would have made such a difference. I just hope other people come across this sight and read these reviews without being sceptical. They really work!!!!!!!!! Thanks again. Much love." — Christine R, United Kingdom

Fruit of the Loom Men’s Stay Tucked Crew T-Shirt 6-Pack

Made from 100% cotton, the Fruit of the Loom Men’s Stay Tucked Crew T-shirt 6-Pack comes with a flat crew neck collar design.

The shirts are designed in a slim-fit style.

The extra length to the undershirts makes them stay-put when tucked in.

The undershirts are available in sizes S - 5XB (Big/Tall). They come in a 6-pack and are available in white, beige and black.

These undershirts are sweat-wicking. This means that the fabric soaks up sweat from your body and releases it through evaporation.

You should note that wicking means there's a high likelihood that sweat transferred from your body will soak your outer garments.

Not only does this reduce the level of comfort you enjoy, but also poses the risk of sweat odor.

When sweat collects, bacteria on the skin begin to break it down, thus causing the sweaty odor we're familiar with.

Here's a bit of positive feedback for Fruit of the Loom Men’s Stay Tucked Crew T-shirt pack:

“I have bought many undershirts looking for something that stays tucked in... until I bought these. They are long! I have gone through entire days without these undershirts pulling out. The quality for the price is good, and I ordered a second package. I will donate all my old undershirts to Goodwill.”

However, customer reviews are mixed. You might find your Fruit of the Loom Men’s Stay Tucked Crew T-shirt shrinking after washing.

Uniqlo Men’s HEATTECH Crewneck Undershirt

The Uniqlo Men’s HEATTECH Crewneck Undershirt promises to keep you warm and comfortable in the cold weather.

Uniqlo Men’s HEATTECH Crewneck Undershirt fabric uses argan oil during the weaving process, leaving the fabric feeling soft.

While argan oil is known more for its culinary uses, it may have side effects.

According to WebMD, some effects argan oil has on the skin, nails and other body areas include:

  • Skin rash
  • Itching
  • Erythema (skin redness)

Since the shirt uses sweat-wicking material, keep in mind the disclaimer regarding odor and soaking as a consequence.

This has an effect when layering your outfits.

The undershirts come in black, white and gray and are available in sizes XS - 3XL.
