It’s almost summer, and you know what that means. Vacations, cool drinks, lying on the beach, you say? Well, there’s that, but there’s also the dreaded underarm wet marks and pit stains that come with sweating through your clothes. Fortunately, plenty of brands out there have wizened up and started making undershirts specifically to help curb armpit sweat – saving your clothes from ruin and saving you from embarrassment.
Top 8 Best Sweat Proof Undershirts

Technology has come a long way toward making undershirts that prevent sweat from leaching into your outer clothing layers while helping you stay cool at the same time. While sweat proof undershirts won’t stop armpit sweat, they can help mask the most embarrassing signs of excessive sweating like visible sweat patches, wetness and yellow stains.
If you’re someone who naturally sweats a lot, a traditional cotton undershirt may not be up to the challenge of stopping your sweat stains and odor. Armpit sweat pads can an a bit of extra protection. But most people can’t stand that armpit diaper feeling.
Top 8 Best Sweat Proof Undershirts
You can also try wearing multiple undershirts, but that can just heat your core body temperature and make your sweating problem worse. Your best bet is to try a specially made undershirt designed to address excessive sweating. Below we’ve collected a list of some of our favorite quick-dry, moisture-wicking and anti-sweat formulated undershirts to help keep you dry and odor-free this summer.
1. Knix Don’t Sweat It T-Shirt
The Knix Don’t Sweat It undershirt is one of the best undershirts for women. It features a fitted silhouette and flexible fabric, along with Fresh Fix Technology in the underarm panels, which prevents sweat from soaking through to your outer layers. What’s great about these shirts is that they’ve been tested by thousands of women to make sure they live up to expectations, so you can be confident that if you go for one of these, it will do the job. If you check out the shirt’s reviews, you’ll see that lots of women report that it can soak up all the sweat they throw at it. Knix is known for comfort and performance – you might also know them from their popular line of undergarments.
2. NUMI Undershirt
NUMI undershirts come fitted with absorbent underarm sweat shield pads for extra protection, so you’ll need to make sure they stay in place as you wear one of these shirts. NUMI offers a line of sweat proof undershirts for women. With its unique Sweat-Secret fabric technology, the NUMI undershirt provides two times the sweat absorption coverage of average undershirts. NUMI undershirts come in three shades of nude, designed to blend in with your skin tone, rather than shouting, “Hey, I’m wearing an undershirt.”
These undershirts are kind of fancy – they’re thin, with a scoop neck, slim fit and laser-cut sleeves that make them practically invisible underneath your clothes. These shirts have the added bonus of being made from TENCEL, a soft and breathable fabric that’s made from ethically sourced eucalyptus trees.
3. Ejis Micro Modal Sweat Proof Undershirt
Ejis is a relative newcomer to the sweat proof undershirt market. Ejis sweat-proof undershirts are produced with a thin single layer that can prevent sweat from absorbing through your outer shirt layer. In addition, the micro modal T-shirt is twice as soft as its cotton counterparts and 50 percent more absorbent. You can find these in white, black and grey versions.
Ejis really stands behind their product. The sweat proof undershirts come with a 100 percent money-back guarantee, so if you don’t feel drier and more confident raising your hands in the air, you can return them for a full refund within the first 45 days after purchase.
These shirts include a large, no-seam, waterproof panel under each armpit to trap sweat and keep it from bleeding through onto your dress shirts. In fact, there are 120 square inches of extra sweat shield under each armpit, so you can feel pretty secure that this shirt isn’t going to let you down.
4. Thompson Tee Undershirts
Thompson Tee is a well-established company that produces several styles of sweat-proof undershirts for both men and women. They hold a patent for Hydro-Shield, a blend of fabrics and moisture barriers that are effective at preventing sweat from bleeding through to your blouse or shirt.
5. Sweatshield
Sweatshield makes a popular and effective undershirt. It’s only available in white, but you can choose a crew neck or V neck style. This T-shirt is made with micro modal fabric, so it’s super soft and effective at shielding your outer garments from sweat stains and odor. This may be one of the best-known sweat proof undershirts currently on the market, and it comes with a 150-percent money-back guarantee, so you can’t lose if you decide to give it a try.
Sweatshield makes sweatproof undershirts for men and women. Their lightweight fabric is comfortable and breathable, and it also helps regulate body temperature.
6. ItsDri
ItsDri makes sweatproof undershirts for both women and men. Each shirt features three-layer underarm pads that pull sweat away from your skin so it can evaporate. The inner layer is infused with copper, which prevents bacterial growth. The shirts come in either beige or white and are guaranteed to keep wet marks and ugly stains off your outer layers.
The ItsDri sweat proof undershirt boldly guarantees that if you wear it, you’ll never have another underarm sweat stain again. Like many of our other options, ItsDri uses advanced fabric technology – copper-infused modal – to make sure this tee soaks up sweat before allowing it to soak into your other layers. It’s body-hugging, too, so you can wear it as a base layer without adding bulk or getting overheated, which would just make your sweating worse.
ItsDri is so confident you’ll love this shirt, they offer a 60-day, money-back guarantee. So you can get a shirt, wear it, wash it, wear it a few more times, and if you don’t love it, send it right back.
7. Nanodri
If your sweating extends beyond your pits, this may be the shirt for you. Nanodri shirts provide sweat protection not only for your underarms but also for your back and torso. These tees are made of fast-drying 100-percent micro polyester and feature a deep V-neck that won’t peek out from under your dress shirts. These are soft and highly breathable shirts that get the job done.
Nanodri, originally developed by a Ph.D. scientist in biochemistry and molecular biology, makes shirts for both men and women that are sweat-absorbent on one side and sweat-repellant on the other. The shirts are antibacterial and anti-fungal, so you won’t have to worry about odor, either. These shirts come highly recommended by people who sweat excessively.
8. Hanes Cool Dri
Hanes Cool Dri shirts are a good option, especially for sports sweat. This is a tee designed specifically for training, so it does a nice job of pulling sweat away from your body during an intense, sweaty workout. These shirts come in a wide variety of colors, but you can also get them in basic, neutral colors like white, gray or black, for wearing under dress shirts to absorb sweat.
If you’ve worn Hanes’ other products, you’ll know what to expect – plain, hardworking, get-the-job-done quality.
Pair a Strong Antiperspirant with Your Favorite Sweat Proof Undershirt
It’s important to remember that sweat proof undershirts won’t necessarily stop you from sweating in the first place. These shirts are designed to help capture sweat, keep it away from your body, and also prevent it from soaking through to your outer clothing layers where the stains and moisture would be highly visible and embarrassing.
But you can always use a strong antiperspirant like SweatBlock to address your overactive sweat glands. SweatBlock’s aluminum active ingredient serves to create a “plug” that blocks your sweat glands, effectively shutting them down and preventing them from releasing sweat. If you apply it at night, it can work while you sleep to set you up for no-sweat success the following day.
Remember that most sweat proof undershirts are manufactured to target the underarm area – so if you have a sweaty chest or sweaty back, you’ll need to choose a tee that provides extra sweat protection for those areas.
A Last Word on Sweat Proof Undershirts
Sweating is a part of daily life, especially during the hot and humid summer months. But excessive sweating caused by diaphoresis or hyperhidrosis is another story. When your sweat glands crank up and underarm sweat starts to seep through your clothes, you can take charge.
Sweat stains are the pits – pun intended. But we’re lucky that technology has advanced to the point that more and more manufacturers are making high-quality, light and effective undershirts that can help us soak up some of the problem.
Give a few of these undershirt choices a try, and you should be well on your way to stain and odor prevention. And when you combine the right undershirt with the right powerful antiperspirant, you can make sure that unsightly, stinky underarm stains are a thing of the past. So, raise your hands in the air – and wave ’em like you just don’t care. Nothing to see here.
