What Are the Best Undershirts That Absorb Sweat?

Sweat stains can be a real pain.

You shower, use deodorant or antiperspirant (or both) and change t-shirts.

And yet, despite all you do and regardless of the time of year, you can’t seem to get rid of sweat stains.

To make matters worse, you may also have to deal with sweat-related odor.

Thankfully, there’s something you can do to radically improve your sweat management.

Consider ditching regular tees for sweat-proof undershirts.

Sweat-proof undershirts are a great way to keep sweating in check. They’re free of chemicals, non-invasive, and prevent sweat stains naturally.

Finding the perfect sweat-proof undershirt can be an overwhelming process, as you have to sift through the options.

To make finding the best undershirts that absorb sweat easier, we’ve rounded up some of the best ones.

Read on for the features, upsides, and downsides as well as a comparison of the best sweat-proof undershirts.

1. Sweatshield Undershirts

From the United States to France to South Africa and Australia, people around the world love Sweatshield undershirts.

And it’s not hard to see why.

Sweatshield undershirts are set apart first and foremost by their Sweat Barrier technology.

The barrier is an inbuilt component of the undershirts rather than a removable pad. This helps it remain effective for longer and makes it wear slower.

Sweatshield’s Sweat Barrier:

  • Absorbs perspiration to avoid sweat stains
  • Includes a comfort layer. This keeps the shirt soft and comfortable
  • Stops odor by directly tackling sweat before bacteria can break it down 
  • Allows heat to escape.

These features make Sweatshield undershirts cool and comfortable to wear every day.

Sweatshield uses micromodal fabric for its undershirts.

Micromodal fibers are thin making it possible to weave them tightly. The result is incredibly thin, undoubtedly strong, and impossibly smooth clothing.

Sweatshield undershirts benefit from the breathability of micromodal fabric. This means that the fabric doesn’t trap sweat to your skin as others do.

Compared to an equally breathable material like cotton, micromodal is 50% more absorbent. This makes it more comfortable to wear all day long.

Another advantage is that micromodal is sustainable and eco-friendly.

Why is this?

Micromodal comes from sustainably sourced beech tree fibers.

Unlike modal and rayon fabrics that are also derived from beech trees, the production of micromodal isn’t heavily reliant on chemicals.

Sweatshield Undershirts are available in crew-neck and V-neck styles for both men and women in several colors.

2. Ejis

Ejis uses silver ions in their undershirts as a way to deal with odor emanating from sweat.

The armpit barrier used in Ejis undershirts features a large waterproof panel in both underarms. This barrier serves the purpose of stopping sweat from soaking the shirt.

The Ejis range includes a scoop neck women’s undershirt, available only in white. Available sizes for women are medium, large and extra-large.

For men, the undershirts are available in three colors; black, grey and white. These come in crew-neck, V-neck and deep V-neck styles.

3. Thompson Tee Sweat-Proof Undershirts

Thompson Tee sweatshirts started about 12 months after Sweatshield.

Though they came up with a similar design, Thompson Tee have their own unique attributes.

They offer sweat-proof undershirts with a proprietary stitching and layering system. Thompson Tee refers to this as Hydro-Shield technology.

Fabrics used include cotton, rayon, and Supima cotton. Cotton is breathable and absorbent but may be prone to staining.

This is a result of a chemical reaction between cotton, the proteins in sweat and aluminum salts in deodorant and antiperspirant.

Sweat-proof undershirts from Thompson Tee are available in styles for both women and men. They come in both slim and original fit styles.

4. ItsDri

ItsDri incorporates a 3-layer approach called Aqua Block technology to design its undershirts.

The first (inner) layer contains copper, giving it antibacterial properties.

Moreover, this helps prevent odor buildup, as bacteria on the skin are to blame for sweat odor.

It’s important to note one key detail about ItsDri concerning size.

There’s a disclaimer that you may need to go for one size higher. The reason for this is how ItsDri designs its undershirts.

The modal material is body-hugging. For some, this may cause the shirts to feel tighter than desired.

One more thing — the shirts are only available in slim-fit form.

ItsDri offers both men’s & women’s styles with a V-neck and scoop-neck respectively.

5. Knix Don’t Sweat It T-Shirt (DSIT)

Knix focuses exclusively on women with a vision of offering clothing that helps them unapologetically look their best.

While they mainly deal with women’s bras and underwear, they offer a women’s undershirt.

The aptly named Don’t Sweat It T-Shirt (DSIT) features sweat-proof armpit protection.

Knix’s Don’t Sweat It T-Shirt features three layers in its design:

  • The first layer wicks moisture away from your body. The company claims it can dry twice as fast as regular cotton
  • The middle layer absorbs sweat wicked away from the preceding layer 
  • The third layer keeps the sweat from overflowing into the sleeve edges.

The Knix sweat-proof undershirt comes in a fitted silhouette. It's designed to be comfortable when worn under clothing. It comes in black, white and beige.

6. Numi Signature Seamless

Numi’s Signature Seamless undershirt is another option exclusively for women.

The Signature Seamless undershirt is available in 5 colors.

These range from the usual black and white to the more deluxe almond, espresso, and caramel color options.

Numi’s Signature Seamless undershirt is form-fitting and comes in several styles:

  • Scoop neck
  • Crewneck
  • Short sleeve
  • Crop top
  • Mock turtleneck
  • Three-quarter sleeves
  • Lace-capped sleeves

At a premium price of $59, this is one of the most expensive women’s sweat-proof shirts currently on the market.

7. Hanes Cool Dri

The Hanes Cool Dri shirt is geared more towards helping people who sweat excessively as a result of working out or sports activities.

It’s made of 100% polyester sweat-wicking fabric. According to Hanes, the fabric is quick-drying.

Hanes refers to its odor protection technology as Cool DRI™. It guards against bacteria that cause odor which gives clothes a sweaty smell.

The Hanes Cool Dri shirts are available in a selection of bright colors. These include neon-bright ones for improved visibility when working out at night.

Additionally, the shirts come in your everyday regular colors (white and black). This is ideal for when you need a more discreet undershirt to go with your outfit.

The shirts come in kids’, women’s and men’s styles and have a 50+ UPF rating to offer protection against UV rays.

8. NanoDri

NanoDri is a Japanese maker of sweat-proof undershirts and sports shirts for both women and men.

The NanoDri sweat-blocking shirt features a dual-layer design.

An inner layer absorbs sweat while an outer one repels sweat. This layer aims to dry sweat quickly thereby warding off bacteria.

NanoDri refers to its shirts as “an all-over sweat blocking solution.”

To this effect, the NanoDri sweat block shirt features sweat protection in the underarms, back, front and sides of the shirt.

Micro polyester is the fabric of choice of these shirts which come in black, white and nude colors.

Their shirts feature a V-neck style, are tagless and are designed to absorb sweat which then escapes via evaporation.

Sweat-wicking is the process of a garment absorbing sweat from your body, dispersing it around the fibers and releasing it through evaporation.

NanoDri markets its shirts as featuring Japanese technology.

What Should You Look for in a Sweat-Proof Shirt?

Before choosing from among these brands, it’s important to consider what you deem as must-haves.

Finding the best sweat-proof undershirt for you entails going over several aspects of the products to find your best fit.

Some of these are covered below.

Sweat-Proof Technology

This is your main concern. If you’re going to spend money on a sweat-proof undershirt, then it better deliver on this.

This attribute must be a core component of the undershirt’s design.

Otherwise, you’d just buy a regular t-shirt (which beats the purpose).

Price

While you’re in search of very good quality, you don't have to part with a fortune just to get it.

All the same, you don’t want to pick the option selling at the lowest price simply because of how much (or rather little) you’re paying.

The perfect undershirt strikes a balance between value-based pricing and high quality, rather than compromising on one in favor of the other.

Design & Style

Since you’re bound to wear them often, the undershirts you go for should fit you and hold up well to everyday use.

When you want to wear them underneath other clothing, your undershirts should be inconspicuous and stay tucked if needed.

On days when you want to wear them solo, they should be comfortable enough and look good without layering your outfit.

Ultimately, you want an undershirt that complements your wardrobe.
