## Description

desertcart.com: Men's Sweatproof Undershirt - Cotton Crew Neck T-Shirt with Underarm Sweat Pads - Original Fit - Aluminum-Free Alternative - White - X-Small : Clothing, Shoes & Jewelry

Review: Works great for preventing sweat-through. Pricey, but worth it. - Why did you pick this product vs others?: If you sweat a lot when having to do a presentation before a group, this might work for you. This has really saved my suits, etc from perspiration. Moisture wicking: Really absorbs perspiration and prevents sweat-through. They are pricey. I paid more for this than almost any dress shirt I own. But it does what it says; and it does greatly reduce the need to dry-clean my suit jackets.
Review: Basically an Armpit Diaper - I stumbled upon this product while researching solutions to my recently acquired sweating issue. I had no idea that such a shirt product existed. So I am writing this for people in that situation too. I have anxiety/stress induced sweating issues. I would not say it’s overly excessive. But I will sweat through my dress shirt every day at work and on weekends I am much better. To the point that I keep a stash of undershirts in my desk to change into after lunch. And I have a system where I shut my door and dry my dress shirt using a space heater. Anyhoo, I am happy with this product in the context of what it is: a diaper shirt. Upon inspection, it seems to have a semi-permeable material (think, the Tyvek sheets that you see around houses on construction sites) sewn into the underarms. With additional cotton layers for absorption… in other words, a diaper. This way, water vapor can get through but liquid cannot. The product is very well assembled and seems excellent quality. The absorbent area is large and well placed. The rest of the shirt is a fairly normal cotton shirt with excellent length to stay tucked-in (regular undershirt manufacturers should take note on Thompson’s length). Basically what happens is, you pee…I mean sweat… like “normal” (if you’re reading a review of this product you’re not normal, by the way) and the sweat absorbs in the designated area but can’t get through that membrane to stain your outer shirt. I can say that it definitely 100% works for me. Now that’s not to say this product doesn’t have some drawbacks. But that does not mean this is not a 5 star product; it does exactly as it says it does. First drawback is comfort. The underarm area has several layers so it’s bulky in that area. And it’s not a cool (temperature-wise) shirt. So if your sweating is more heat-related and less stress-related this shirt might be an issue, I’m not sure. Also, by later afternoon you’re going to have a full diaper. It’s soggy and can be uncomfortable. Albeit, your outer shirt will be stain-free. The other thing is, you can really only wear this with a long sleeve outer shirt, maybe a polo would work. If they could invent something to be worn under a regular t-shirt that would really be something. Based on my experience and looking at other reviews, you may find the sizing tricky. I can tell you that I normally buy large undershirts and a L Thompson was perfect (it was a tad smaller than expected but that turned out to be a good thing). You want this shirt to be on the tight side so it’s effective. Overall, I would say this product works and deserves a 5 star review. I will be buying a few more so I can wear them daily to work. I have worn it 3 times and washed it twice. At first, you’ll notice the membrane has a bit of a crinkle noise to it when moving but this went away after it starts getting wet from sweat. It launders pretty well but I did notice that perhaps the cotton shirt shrinks at a different rate than the membrane material so it seems bulkier after the initial wash.

## Questions & Answers

**Q: Who are Thompson Tees for?**
A: Thompson Tees are for everyone! Whether you have a medical condition and are looking for a natural alternative for excessive sweating or need a nervousness barrier, we've got you covered! No more sweat stains means confidence and comfort every day.

**Q: Original Fit vs Slim Fit: Which one is right for me?**
A: Slim Fit shirts are made with rayon and spandex and are intended to fit snug, so they’re more discreet underneath your clothing. Original Fit is made from 100% cotton & provides a little more breathing room for those who prefer a looser undershirt.

**Q: How is the Thompson Tee different from other "sweat proof" shirts?**
A: The Thompson Tee is the original sweat proof undershirt. It's the only undershirt backed by a patent from the U.S. Patent Office for our Hydro-Shield sweatproof technology, which completely absorbs & blocks sweat with breathability.

**Q: Is the underarm barrier really sweat proof?**
A: The Thompson Tee is the only patented proprietary design that uses a clinical-grade sweatproof material that completely blocks moisture from passing through. So you can be sure that the shirt won't lose its effectiveness over time, wash after wash.

**Q: What's the story behind the Thompson Tee?**
A: Spurred by their struggles with hyperhidrosis, a medical condition causing heavy perspiration, friends Billy Thompson & Randy Choi, joined forces to create the Thompson Tee, a sweatproof tshirt solution to the embarrassing sweat marks and stains.
