For some people, buying undershirts is an afterthought. But if you sweat heavily throughout the day, the sweat proof undershirt you choose is key to helping you manage your day-to-day.
But it’s more than just blocking sweat. We know that you have distinct fit and style preferences. To help you purchase the right Thompson Tee for your needs, we created a style guide based off personal experiences and real customer feedback to help guide your purchase.
How Thompson Tee’s Sweat Proof Undershirts Work
We designed our sweat proof undershirts to conceal any trace of underarm sweat. Every undershirt has a patented, clinical-grade sweat proof material called Hydro-Shield that blocks moisture from passing through. Our shirts differ from "sweat resistant" and "moisture wicking" shirts, because they absorb sweat rather than wick it away across other areas of your body.
Other sweat proof shirt competitors use chemically treated material that washes out over time. The Thompson Tee Hydro-Shield technology, on the other hand, has native properties — meaning the sweat proof technology is part of the fabric and won’t lose its effectiveness over time.
When wearing an undershirt nearly every day, you need a product that will last — and protect your clothing investment. At Thompson Tee, we use premium combed cotton and high-quality rayon from bamboo to create superior sweat proof T-shirts. We choose to use bamboo because it's an ultra-soft, durable material that hugs the body, just as an undershirt should.
Which Fit Is Best? Slim Fit vs. Original Fit
For most people, the shirt and size you choose will ultimately depend on your fit and style preferences.
Both our men's and women’s sweat proof T-shirts come in two main styles: Original Fit and Slim Fit. Both fits are made with our patented Hydro-Shield technology that traps sweat and allows it to evaporate rather than soak through your shirt.
Slim Fit shirts are intended to fit snug, making them more discreet underneath your clothing. The Original Fit provides a little more breathing room for those who prefer a looser undershirt.
If you're looking for the most sweat protection but like the fit of a typical T-shirt, you may want to try a size up in the Original Fit shirts.
What Size Should You Buy?
We created our sweat proof Thompson Tees to follow typical T-shirt sizing. If you wear a size large in most undershirts, you will probably want to order a size large in your Thompson Tee. Our Slim Fit undershirts are intended to fit tighter than the original version.
Here are both our men’s and women’s sizing charts for reference:
Beyond body measurements, there are a few other factors that could affect the size and style that suits you best.
How Much Do You Sweat?
All Thompson Tees are guaranteed to block 100% of underarm sweat. But if you're looking for the most sweat protection possible, it's important to know that our sweat proof underarm panels are scaled to size, meaning a size 2XL shirt will have a larger underarm barrier than an XL, for example.
What women need to know: Due to design limitations, our women’s shirts have smaller underarm barriers than the men’s styles. However, they are also scaled to size, so if you’re in need of more sweat protection, try a size up.
Among extreme sweaters, some women prefer to wear men’s shirts for the extra sweat protection. We offer XS sizes for both our Regular and Slim Fit Men’s shirts, which could be a great option for women who experience severe axillary hyperhidrosis.
Which Necklines or Colors Do You Prefer?
Choosing the right Thompson Tee also depends on your style. Think about what you wear daily. Do you wear suits or dress shirts often? If so, the Slim Fit option may be a great choice. If your daily wear is much more casual, the Original Fit will do the job.
The bottom line? If you're still unsure about which sweat proof Thompson Tee is right for you, try one risk-free today. Yes, it's that easy — you're welcome to put it to the test for 30 days (wear it and wash it!) to make sure you've found the perfect solution for your underarm sweating.
