Here Are the Best Undershirts for Stopping Pit Stains
Comfortable everyday wear options with effective sweat-blocking features.
Uncertainty isn’t the feeling you want when it comes to sweat protection.
If you’re someone that’s experienced so-so results when it comes to anti-perspirants—even those considered extra-strength—then you know just how frustrating and fragile that protection can be.
Maybe you hold up fine some days but others not so much.
Or maybe it’s a sudden stressful situation that sends your sweating over the edge and you find it hard to prepare for those moments.
Whether your sweat is situational or hyperhidrosis, one of the best ways to regain sweat protection certainty is wearing an undershirt that’s specifically designed to handle heavy sweating.
The most popular underarm sweat blocking feature is the underarm sweat pad, which is a built-in pad or several layers of fabric at the underarm to catch and absorb sweat at a much higher rate than a traditional undershirt.
Other specialty undershirts feature innovative new fabrics and materials that quickly absorb and evaporate sweat at a higher rate than traditional undershirts so that it’s unable to pool and spread to your outer layer.
Whatever style or level of sweat protection you might need, the best thing about sweat proof undershirts are their consistency.
You know what you’re getting day after day and from one situation to the next.
Here, we’ve put together a collection of the best undershirts for stopping pit stains with picks that feature both underarm sweat pads and quick absorption fabrics.
Here’s How We Make Our Sweat Stoppers Picks
We know what works and what falls short because we’ve been through it ourselves.
From extensive testing of undershirts, underwear, and socks designed to block sweat and odor, including our own personal experiences dealing with hyperhidrosis, we’ve found that 2 key characteristics make for a great sweat stopping undergarment.
1. Proven Sweat-Stopping Technology
Impressive new fabrics, technologies, and design features have led to incredible strides in sweat-blocking undergarments that can address a variety of sweating conditions.
Keep in mind, however, that while many garments are marketed as effective sweat blockers, some options carry out that protection better than others.
We went with undershirts that you can put on and not give it or sweat another thought.
2. Easy Everyday Wear Integration
It’s not enough just to effectively block sweat, as there are any number of ways this can be achieved.
A high-quality, sweat proof undershirt will absorb sweat, create a comfortable barrier between your body and top layer, and fit well without adding extra bulk.
You want an option that will seamlessly integrate into your daily wardrobe and hold up through whatever the day throws at you.

Here's How Undershirts Can Help to Prevent Pit Stains
Of course, pit stains aren’t the worst thing in the world.
After all, everybody sweats, just some more in certain areas than others.
However, having a big pool of underarm sweat is also far from ideal.
First off, that damp underarm area on your undershirt can be pretty uncomfortable and actually lead to painful rashes if there’s too much friction in the moist area between your arm and torso.
Not to mention, pit stains have a tendency of making you feel self-conscious and distracted.
However, opting to wear an undershirt can help with preventing pit stains by providing an absorbent barrier between you and your top layer.
If you lean more toward the mild end of the sweat spectrum, an everyday undershirt should cover the majority of your sweat control needs.
However, if you’re more toward the heavy end of the sweat spectrum, you’ll want to choose an undershirt specifically designed to target sweating with specialty design features and fabrics, such as the options highlighted above.
