These WORK! Life-changing!
Not often that I can say a piece of clothing has changed my life. Being a pretty big dude, when I get hot I tend to get drenched. As I often wear long sleeve dress shirts for work, this has always been somewhat embarrassing. These undershirts work. They really keep the moisture off of me and off my shirts. They somehow dissipate it off into the air. I had a few that arrived in my order with a tiny hole near the neckline. Not a big deal but I did let the seller know in case it was a batch defect. They immediately sent me replacements. Excellent product and customer service! Be sure to wash these on ‘delicate’ and do not put in dryer. Hang up and let them air dry.

Best t-shirt ever
Chronic sweat factory here, these shirts are my absolute favorite. I have them in 3 colors and wear them as much as humanly possible. Got a flight? this shirt. Going to the mall? this shirt. Driving long distance? this shirt. Meeting my bf's family? this shirt. No matter how hot and sweaty my pits get, they have not once soaked through. I'm usually a men's Large t-shirt, and the size Medium fits me a little baggy, whereas Small is snug and comfortable. The padding is thick and can take a little time to get used too, but after a while it feels like a regular t-shirt. The underarms get a little poofy after a few washes, but they flatten back down as you wear it.

No more hiding my saturated arm pits under a black jacket!
I have never written an Amazon review before, but this Thompson Tee was so incredible, I feel compelled to do so!! I heard of this product from a recent article in Buzzfeed for people that perspire more than others. It could be 45 degrees outside, and I will be sweating. I'm just one of those guys, I'm always running hot temperature wise, and my wife calls me a "furnace." When I am at work (Furniture Sales) I am constantly running around the sales floor, lifting and moving heavy objects, working with the public, etc. By 11:00am, my arm pits are already saturated! I wear a black sports coat all day in order to hide my perspiration stains. When I read about Thompson Tee's, I was skeptical. And the price is $30, not exactly cheap! But I decided to try it. At first, upon opening the package, I thought the overall material was too light weight, and the V-neck was cut too low! But I later realized after putting it on, that this was perfect for not feeling a "heavy" under shirt, and the with the lower V cut, all of my button up oxford shirts do not show that I am wearing an under shirt! That is very well thought out, and my wife loves not having to see my undershirt poking out anymore!! So, how does it hold up with sweat? All I can say is HOLY MOLY!! You can feel the sweat pads soaking up everything, and never once bleeding sweat stains through the shirt!! I was completely shocked that for the first time in decades, I was not having to hide my sweat stained shirt under a sports coat!! Talk about re-newed confidence!! I could not believe that not once during my 10 hour shift did I EVER show any perspiration on my oxford shirt! And it has continued to work every time after washing as well!! I am ordering several more of these, because at $30 per investment, they are also saving my expensive sports coats and suits from constant dry cleaning bills, and costly replacement!! I HIGHLY recommend Thompson Tee if you excessively perspire under the arms!

SIZE IS WACK!!!!
The sizing is whack. First, Amazon recommended a large, which I got, but it came out to be as large as an apron. Then I sent it back and switched to a medium, which was still very big. I am stuck with two pairs, which I need to send back for the 3rd time to try a small; maybe it will fit. This has been a journey with their sizing, though the material is solid.

Works as advertised, but creates a new problem...
I want to start by saying, you absolutely get what you pay for with this product. It really does capture all the sweat and will keep whatever shirt(s) you're wearing over top it of dry. However, after a few months of wearing it once or twice a week, a new problem arose. The washing instructions say to be sure that it's inside out and to use warm water, which I always follow (this shirt catches every drop of sweat, so trust me, it's gross by the time you take it off... you wouldn't want to clean it any other way). The problem I mentioned earlier is that once you've worn it enough times, even if you've been following the proper cleaning instructions, after about four hours of wearing the shirt it'll start to smell like you have two smelly wet gym socks tucked up under your arm pits. I've even tried washing them twice before wearing them again, but it doesn't help. So it creates this issue of "do I want to have no pit stains, but smell like I just came out of a locker room... or do I opt for pit stains but at least smell better?" Mind you, I still wear deodorant, but the smell over powers it. I'm not sure if these shirts have a 'shelf life' or something where after a certain number of uses you're just going to have to endure your own odor, but I just wanted people to be aware of this. Again, the shirt does exactly what it says it will and it does it well, but after enough use, you may want to consider wearing a newer one because like people say "if your body odor is strong enough that YOU can smell it, than other people can definitely smell it too".

Functional and Comfortable
Amazing product! I’ve tried every kind of undershirt imaginable and none could get me through an entire work day without sweat stains showing through my shirts. By referral from a friend, I purchased 2 regular v-necks in black and white and a deep v-neck in grey. They’ve all worked perfectly! Will be ordering more to get me through an entire work week as soon as I finish writing this review. Be sure to order the correct cut!! I ordered a large regular cut in these but almost ordered the slim cuts by mistake. From what I understand, the slim cuts are VERY slim. The regular cuts I received were perfect to go under a large size buttondown or sweater. Also, the deep v-neck is very deep. Comes all the way down to the bottom of my sternum. Great for leaving the first few buttons of a shirt undone without an undershirt showing.

If you want a REAL & THOUGHT-OUT review then read on......
If you want a REAL & THOUGHT-OUT review that isn't just thrown at you by a bitter person read on..... If you actually work at a fast physical pace and don't want to ever have to deal with underarm sweat, even having hyperhidrosis or not, this is the best thing you can buy. If there is anything anyone dislikes about how well this undershirt works, I honestly mean no offense, but they need to Seek Medical Attention Immediately for any number of possible medical issues. What I mean by that is if this doesn't completely hide your exterior sweat issues then I can vouch for the fact that there are not other options besides seeing a doctor. I have hyperhidrosis (already seen a doctor for it) and I ruined my entire wardrobe out of denial and stupidity, plus having to try other cheaper attempts at a medical solution before my insurance will cover Botox. I sweat so severely that I've tried absorbing pads meant for under the armpit, I've tried other solutions like panty liners and I've tried other under shirts with similar padding. In the past I've picked shirts meant to show as little sweat as possible so when I'm at work I don't look disgusting because I have so much sweat under my arms. I can honestly tell you after trying this product on my busiest hottest most active days... It. Didn't. Show. Anything. Now, if I was being pessimistic I would consider saying something like 'it makes you sweat more because it's so thick and makes you hotter'. HOWEVER, all undershirts will have that effect and 'WHO CARES?' because no one will SEE the sweat and it WICKS it right up under your armpits. As a matter of fact at the end of my sweatiest day this month my armpits felt drier than the rest of my torso and back because of the absorbent material under the arms. Because of this shirt I have finally felt for the first time in a year-and-a-half that I am not wasting my money rebuilding my whole stock of completely ruined shirts. I actually spent hundreds of dollars on new dress shirts because I finally feel like I won't ruin them in 2 wears anymore. Sizing was spot-on for standard t-shirt fitting. However, keep in mind that you may want your undershirt to be a size smaller so it is not as easily seen underneath another shirt or cause extra wrinkles under a dress shirt. Not a bash on the product though. Lastly, as far as it holding up in the washer I haven't had a single problem with it and I have washed my first two shirts five times with a little bit of detergent, vinegar water, and dish soap each time. Now, it's just an opinion, but I think that anyone who complains about it getting holes after one wash or not holding up in the washing machine should consider actually using that setting labeled 'gentle' or consider getting a new washing machine. Bottom line is it holds up just as well as any shirt I have, and better than ones that cost twice as much. "This is what all undershirts should be like."

More comfortable and effective than expected
I have always had slight over-perpetration issues, but recently I have no longer been able to comfortably compensate for this issue with wardrobe modifications and anti-perperants because I was prescribed 75mg minocycline 2x daily for acne reduction, which caused my sweating to become extremely excessive. I had never before dealt with this amount of sweating before, and even regular undershirts wouldn’t do the trick, and were also less easy to hide under clothes. This product is meant to be worn UNDER another shirt that would usually cause unwanted amounts of perspiration. For this use of the product, it was simply impeccable. The product I received was slightly looser-fitting than I presumed, but I instantly understand when I put it on, feeling the comfortable looseness and mobility provided, and also the nice gap between the sweat pad and my underarm. This product is very easy to conceal because of the deep V neck, and also very effective at catching perspiration. Under a sweater, dress shirt, AND a wool coat, not a single drop of sweat passed through the pads. It tucks in great under any pair of pants (or shorts if you’re still able to pull of a style like that), and it’s great to finally feel confident wearing casual dress clothes without worrying about excessive perspiration, and being able to take my acne medication every day. Despite the sweat being captured in the pads, I found it very easy to adjust to because of the looser fit, and definitely more comfortable than wearing regular clothes with sweat caught in the underarms. I would reccomend this product to anyone with light or excessive sweating who is looking for a way to stop perspiration under their current wardrobe, or anyone with light sweating who is looking for a healthy alternative to anti persperant and still willing to continue deodorant usage.
