For some people, buying undershirts is an afterthought. But if you sweat heavily throughout the day, the undershirt you choose could affect your focus and confidence.
We designed our sweat proof undershirts to conceal any trace of underarm sweat. But we also know that you have distinct fit and style preferences. So to help you purchase the right Thompson Tee for your needs, we devised this style guide based off personal experiences and real customer feedback.
Slim Fit Vs. Original Fit: Which Is Right for You?
Both our men & women’s sweat proof T-shirts come in two main styles: Original Fit (Cotton) & Slim Fit (Bamboo). Each include our patented Hydro-Shield technology to trap sweat and allow it to evaporate rather than soak through to your shirt.
When wearing an undershirt nearly every day, you need a product that will last — and protect your clothing investment. We use premium combed cotton and high-quality bamboo to create superior sweat proof T-shirts. We chose to use bamboo because it's an ultra soft yet durable material that hugs the body, providing a slimmer fit compared to the cotton version.
We created all of our sweat proof Thompson Tees to follow typical T-shirt sizing. So if you wear a size large in most undershirts, you will probably want to order a size large in your Thompson Tee. However, it's important to know that our Slim Fit Bamboo undershirts are intended to fit tighter than the Original version.
Beyond body type, there are a few other factors that could affect the size and style that suits you best:
1. Your Sweating Level
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. However, they are also scaled to size, so if you’re in need of more sweat protection, try a size up.
For extreme sweaters, we’ve found that some women prefer to wear Men’s shirts for the extra sweat protection. We recently rolled out 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.
2. Your Fit Preference
For most people, the shirt and size you choose will ultimately depend on your fit and style preferences. For example, both our Men’s and Women’s Slim Fit Bamboo 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.
3. Your Style Choices
Do you wear slim fit dress shirts and want a T-shirt that also conforms to your body? That’s exactly what the Slim Fit bamboo option was intended to do.
For the guys who want to hide the fact they're wearing an undershirt (and show a little chest), the Men’s Original Fit Deep V-Neck is also a great option!
