Men's Cotton Sweatproof Undershirt, Odor & Sweat Blocking, Crew Neck

This is my review of the Thompson Tee Regular Crewneck shirt in the large fitment. It was a week before my interview and instead of preparing myself mentally, I was dreading the future event immensely...I've been a sweaty person most of my adult life and I ONLY sweat under my armpits. It does not matter if its 10 degrees outside or if I'm in the driest place on Earth my pits will always be super saturated. I've noticed over the years that around certain people, like my immediate family and really close friends, I do not sweat around them. But again, this is never 100% I would say its about 30/70, 70 being the chance that I will sweat around really close ones. Unfortunately, if we are doing anything in public is supersoak time. And By the way, when I mean I sweat under my pits, I don't mean those little 2x1 sweat pits, I'm talking I'm talking sweat rings with the diameter of like 8 or 9 inches! Sometimes more!!So if you can relate to this then please listen! I ordered the shirt as a last ditch effort, subconsciously KNOWING it would not work for me because I sweat A LOT. I received the package very fast in fact, a few days earlier than expected. When I opened it I was shocked at how thick and dare I say: Diapery the hydro-shield was. I felt let down because during inspection (holding it up to a light), it looked like a thick piece of cotton that you can see through. And we all know that no amount of cotton can stop our sweaty armpits. Later that night, when my wife and I had to go to Wal-Mart, I curiously slipped on the Thompson Tee and wore a lime green shirt over it. By now, you understand that I can sweat through that in less than a minute...but I wanted to put it to the test before I wore it to my interview. I checked my pits every ten minutes or so and nothing at all every time.It did not make and detectable noise for me to hear. And it felt like a warm towel under my armpits because it absorbed the sweat really well. The shirt manufacturer states that the sweat absorbed will evaporate with the natural bellow-like movement your arms create when moving them. It isn't like you have to go around flapping like a bird, instead its the natural movements for example: moving your arms walking, lifting things up, any action that sways your arms up down or side to side, etc. Success!, a whole trip without sweat marks on my outer shirt I was SOLD, I turned the shirt inside out and allowed the shirt to dry so I could use it during the interview. The next morning, and I'm getting ready for my interview. I had full faith in my Thompson Tee and wore a ultra light blue long sleeve polo( a shirt my wife bought me that I never wore). I was nerve wracked but this time it was not because of my sweating it was because of the actual interview. FAILURE, I looked down late in my 2 hour interview and my heart sank. The sweat had made its way under the hydroshield and I had sweat marks in the midsection of my ribs. That only made me more nervous and the remaining time I was no longer looked confident as I had to hold my arms kinda like a t-rex to try and hide my sweat. After I got done with the interview I sprinted to my truck. I was honestly devastated but I was intent on making my purchase worth it so I tried to figure out what went wrong. I believe it was the fact that it was long sleeve. I would highly recommend not wearing a long sleeve shirt if you have hyperhidrosis like me and plan on sitting down for 2 hours of an intense nerve wracking event. That being said I actually got the job. When I went to orientation I knew they would throw me in a blue uniform and put me to work so I wore my thompson tee and a white nike dry fit over it. The uniform had not came in yet so they handed me a grey shirt. I went to the bathroom and decided to just put the grey shirt over both the thompson tee and the nike dry fit. I worked from 7am til 4:13pm that day and NOT A SINGLE SWEAT MARK!!!!!!!!!!!!!! I was so excited I wore the three shirt all day until 9pm and still nothing!! I was amazed at how adding a thin breathable shirt like a nike dryfit over my thompson tee completely fixed all my problems. The thing is that your armpits get so sweaty because there is usually always pressure on your shirt in that area. I admit the sweat leaked under the hydroshield just as it did during the interview but working all day and not sitting down stressed out helped alot and I believe another shirt is all you need to stop that under the hydroshield sweat because you dont have a lot of friction on your ribs the whole day. It worked for me and it will work for you too buy one and test it out I'm only 19 years old and I would spend my last $25 dollars on this shirt if I had to. I've used it approximately 6 times already and it works every time. I plan on using my first check to buy 5 of them for the work week! Don't live your life wearing only black shirts like I did, I'm speaking from the heart IT WORKS. -Stevan **** UPDATE**** Here is an update over a year after this review! I've since acquired 3 more Thompson tees and wear them every day I work. I still work for the same company which supplies us with a blue uniform shirt, a color that I could not ever wear during my adult life before Thompson tee. I also still have my very first Thompson tee and it works the same as it did the first day I wore it. A year ago I told y'all that perphaps wearing a long sleeve shirt would hinder the Thompson tee. I found that to be false as I mainly wear a long sleeve shirt at work and have never seen a drop of sweat on it. I also stated that I stated that wearing a thin shirt over the Thompson would full proof it. That indeed is still true but I've found the MOST effective way to use the tee shirt is to avoid wearing tight t shirts over it. I'm not saying you have to wear a oversized shirt, just not a tight one. I found evaporation of sweat gathered by the Thompson tee is most effective outside where air is circulating through wind and the sun is drying out the sweat. But do not worry as I've worn it inside all day plenty of times and still no sweat. Keep in mind that the sweat does seep under the padding of the Thompson tee but it will not show on the outer shirt as long as there isn't continuous pressure in that area for a long time. Just the contact of it against the Thompson tee will not make the outer shirt wet. ***Update*** 10 years later and almost 30 years old and I still work for this same company. I've since worked my way up in the office but guess what I have under my dress shirt? You betcha! I usually buy a fresh set of shirts every year. Life changing product.

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.

I just bought 5 of these crew neck shirts. They were delivered yesterday and I wore one for the first time today under a solid blue shirt guaranteed to advertise sweat like a neon sign. Nothing! For the first time in my life I didn't have pit stains by 9:00 AM. And I still didn't have a single dark spot on my light colored blue shirt at 7:00 PM. These shirts work. Now for some feedback on fit & feel. I saw some reviews here that talked about how huge these shirts are and how a medium would fit someone 6'6" and 220 lbs. Happily, I ignored those reviews and ordered the Large size I usually buy in a Hanes tee shirt thinking that the size couldn't possibly be that far off. The fit.....I'm 6'0" and 200 lbs. I have a 45" chest and 34" waist. I wear a 44 Long jacket and shirts with a 16 1/2 collar and 34/35 sleeve length in a "slim fit" cut. The Thompson Tee in size Large fit me as I would expect a normal Hanes size large to fit. It wasn't huge or oversized at all. It looked and felt just fine under a slim fit dress shirt. The pads.....some reviewers indicated that they are too thick and noticeable. I put the shirt on and for the first 5 minutes I was aware of the pads. That's about it. Not uncomfortable, not huge, just aware something was different. After those first 5 minutes, I pretty much didn't notice I was wearing the Thompson Tee Shirt the rest of the day. Good enough for me. The cotton.....these shirts feel like a premium cotton. Very soft and smooth. My usual Hanes tee shirts feel like sandpaper in comparison. These shirts feel better next to your skin. The two downsides that come to mind are cost and availability. At $25, these things are expensive. And they aren't available anywhere locally for me. But, my order arrived within a week so I can handle thinking ahead when I need to replace them. And while the cost may seem exorbitant I'll throw out two thoughts that sold me on these shirts. 1.) They actually stop the pit stains. I don't have to be embarrassed any longer. I can wear something other than white shirts. 2.) I will no longer be throwing out $65 dress shirts (and shirts I really like) every few months because of pit stains. That should offset the cost of the Thompson tee shirts. Perfect? Yeah, they pretty much do what I wanted and hoped for out of the package. I'll have to see how they hold up over time. But for now, I'm sold.

I read most of the reviews before spending nearly $30 on this shirt and while the majority of them were positive, some of the negatives ones were troubling. However, after only one day of wearing this shirt I am very satisfied with it's performance and will be purchasing several more in the future. I have always, since puberty, sweated heavily under my arms - soaking through max strength deodorant, an undershirt, a shirt, and sometimes even a light coat of sweater. I bought this Thompson Tee in the hopes of being able to stem the tide and reclaim my nicely colored shirt and confidence without worrying about the giant dark sweat rings! Pros: 1. It works. It prevents the sweat from reaching your outer clothing. I wore it an entire work day beneath a dress shirt and a coat.. and still have a dry work shirt! No rings, no stains. 2. It's comfortable, it fit as expected (I got a large and wear a 34/35 dress shirt). It's soft, form fitting, and stayed tucked in. Cons: I do not consider these as a fault of the product, but they are worth mentioning. 1. You will still sweat.. and yes, as others have mentioned, the pads will hold sweat against skin. You can feel it. It's not uncomfortable, as it is something I've dealt with for the past 20 years, but it may be off putting to some people. And yes, it does create a "billowing" effect to draw air into your underarms, but if you sweat excessively (like I assume you do) it will not entirely dry up. 2. The under padding in the arms does take some getting used to... it's just thicker beneath your pits, but again not uncomfortable. There is sort of a diaper effect, but I expected that. The bottom line is that this thing kept my dress shirt dry - it gave the appearance that I do not sweat. Nice, clean, dry under arms after a 10 hour day of wearing a long sleeve shirt and coat. I took off the coat to eat lunch and behold, no rings! It was an enjoyable difference to be able to wave at people or give an open armed hug. If you just want to keep sweat off your shirts and out of public scrutiny, this shirt will do it. I plan to update this review after I see how well it holds up to constant sweating and washing. UPDATE: This past weekend I wore my Thompson Tee to take family photos in lightly colored dress shirts, which is always a nightmare for me. I am so happy to report that after being caught outside in the afternoon sun for over an hour, my baby blue dress shirt was dry as a bone! It is the first time in decades that I comfortably and confidently had photos taken without worrying about keeping my underarms hidden. That seals the deal, Thompson Tee's are my undershirts from now on.

This undershirt works really well! The cotton fabric is soft and comfortable, and the built-in sweat pads make a big difference in keeping shirts dry. It fits nicely without feeling tight and is easy to wear under work clothes or everyday outfits. A great option if you deal with sweating and want extra confidence throughout the day.

I have suffered severe hyperhidrosis since I was a teenager. It was something I suffered in silence... for a young woman, it was quite embarrassing: I couldn't wear cute colors, cute clothes, and had to always be secretly daubing at my dripping underarms with napkins or tissue. Fellow-sufferers know just what I'm talking about. Severe hyperhidrosis can be -- no, correction; IS -- a socially-debilitating condition. It is truly awful. Now in menopause and my early 50's, my sweating thankfully has reduced significantly. BUT the great news is that you -- the younger heavy-sweating folks of today -- have a non-surgical and drug-free solution in this fantastic new shirt. Wow, how I wish this product was available 20-30 years ago. I can't even imagine how awesome this would have been to have had in my ealier (heavy-sweating) days. ONE OF MY THREE SONS had the unfortunate luck of inheriting my hyperhidrosis gene. He has hyperhidrosis bad. He sweats bullets, buckets; it's okay for guys to sweat though, right?!? ... I thought "oh it's good you're not a girl," but trust me it's still bad for him. He's told me this often. And it DOES bother him. He's in college now, and he recently sent me a photo of his sweat marks and said, "Mom, this is just ridiculous... there has to be something I can do for this." I went online to continue my search for solutions, as I have done for the past several years for both my sake and his. We have looked into alternate solutions like drugs, and extreme solutions like botox and surgery. None of which we are willing to do for various reason which I won't go into here (although certainly money is one of them.) Then... something promising! I stumbled upon the Thompson Tee while doing more Googling (sweat-proof shirts, no sweat clothing, etc.) After reading the description, checking the reviews on Amazon, and then further exploring the Thompson Tee website, I was convinced this was at least a very good step in the right direction! But I was reticent to get too excited just yet because the "footprint" of the underarm barrier didn't look nearly as big as the sweat stain in the photo my son had sent me. I thought, "surely he would sweat right through this thing, right?" So I contacted the people at Thompson Tee via email, explaining my doubt that this would work for my son's particular case. This was their quick reply: "Have you tried our shirts yet? Our Hydro-Shield has an absorbent layer that will absorb more than a regular shirt will, so it's protective ability is greater than what the sweat mark on regular shirts show. All our shirts come with an unconditional guarantee even if they've been worn/washed so feel free to try it out." Now I was really encouraged. I was so hopeful that I ordered one for my son right away. But I still didn't want to believe this could really be a solution until we actually tested it out. Or rather, my SON tested it out. So fast-forward to Christmas break, the order arrives, my son is home from college and available to test out the new "sweat-proof" shirt. He first wore it to a friend's house one night, and said it worked fine. But it was a low-key evening; not a really good test of the tee shirt. The real test was going to be a few nights later when he went to a night club where there would be LOTS of old and new friends to meet, lots of dancing and socializing, and most likely an overly-warm temperature in the place. From my memory of my own hyperhidrosis, this would *definitely* be one of the best tests for the tee. The results came in the day after the big evening: I asked him how the shirt worked and if it helped. He grinned in amazement and said, "Wow, Just Wow! I really thought it would be soaking wet and uncomfortable, because I know I sweated A LOT. I thought the sweat had to be showing somewhere ... but somehow it seemed to absorb it all. I totally had Z.E.R.O. wet stains on my shirt. It helped a TON!" So if you've read my review this far, my advice is this: Go give this shirt a real test drive as soon as you can. The company has fantastic customer support, and you can return it after 30 days even if you've worn and washed it (and sweat in it, haha) with no strings attached! I'll bet if you really do have severe hyperhidrosis you will be singing praises for this product, too! Thanks Thompson Tee inventor.

I'll try to be brief with the positives: This product is amazing. Like all the other reviews that gave the Thompson Tee 4-5 stars, these shirts changed my life. I was a heavy sweater since high school. At work (where I am required to wear suits everyday) I would leave my jacket on all day to hide the sweat stains on my dress shirts. Now I go to work without any fear or hesitation in taking my coat off and lifting my arms. This product works. I figured instead of going on about how happy I am with this product, I would share some side considerations for potential buyers. First, the sizing fits the same as other brands of undershirts I've bought in the past (Under Armour, Calvin Klein, Hanes, Jockey, Fruit of the Loom). However, I do feel that the length is a little short. There are a couple inches to tuck into my pants, but after regular walking, moving around, and reaching for things; that short extra length comes untucked under my dress shirts. I would say I'm average height as well. Not a huge deal, but I wish they were a little bit longer. Second, for the reviewers who talk about having a wet diaper in their armpits all day when they wear this shirt, I think that's a small price to pay for avoiding embarrassing, shirt-destroying pit stains. Yes, the pad is thicker in the armpits, and it does get moist and soggy. But after wearing these tees for a month now, I will say they dry fairly quickly while you're wearing them. For example, I might get sweaty running papers around the office, or walking outside to get lunch; but when I'm back at my desk, sitting for a little, the pads dry right up. Most importantly, when I was wearing regular undershirts, they were just as soggy too. I'd rather have moist armpits in a tshirt that doesn't show, than moist armpits with a tshirt that does show. Not sure why people are complaining. Third, the tees did make some swishing noise (like windbreaker athletic pants) when they were fresh out of the package. But after a few wears and a few times in the wash, I feel that the plastic-y noise is gone. And even when they were brand new, nobody heard at work. It was a very faint swish that the wearer could hear. All in all, if you're suffering from pit stains, there is really no reason to not give this tshirt a shot.

The sweat protection for the underarms is outstanding. It absorbs all sweat, even from a heavy sweating in hot weather. Impressive how well it works. However, the fit is really bad. I purchased the original fit and a size larger than I order everything else and it still is skin tight. That would be nice for business use in a suit/dress shirt but at times you want a little more relax fit, looser and more comfortable. They have no option other than original and slim fit. Can't imagine how tight slim fit would be as this one is already skin tight and it is full size larger than all my shirts.

I bought already 5 of these T-shirts. They get delivered fast and the product is very efficient in retaining sweat and avoiding embarrassing wet marks under the armpit. I personally prefer the crew neck and original fit as the slim fit is made of different material and I found it a little more warm. It take a while to dry after washing due to the pads under the arm but with couple of them in the stock I sort out the issue quickly. Overall I am very satisfied with this product and I also recommend it to friends and family. I will definitely buy it again if needed

Wow. Was skeptical at first considering how many dress shirts I've ruined with sweat or how many times I'd have to change halfway through the day. How could a t-shirt fix all of that? Well, this shirt did. I can wear colors again! Who knew! This shirt works better than expected. Much better. I'm a student and wore this shirt under a light grey dress shirt the other day when I had an exam and interview within 20 minutes of each other, so you can imagine how stressed (and therefore sweaty) I was. To my surprise, not a single droplet of sweat showing under my arms. Safe to say I love this new shirt. Not only am I saving dress shirts and am able to wear new colors I'd never dare wear before, my confidence has been boosted considerably since I'm no longer worried about the embarrassing underarm sweat marks. It does fit a tad big. I'm normally an XL, however, a large in this shirt fits me perfectly. Not too tight that its restrictive or uncomfortable, but not too big and baggy that it's not a good undershirt or that the sleeves bunch or ride up. I'd recommend getting one size smaller than you'd get in a normal t-shirt (you want it to be relatively snug). There are some things to be aware of though. The armpits are padded to absorb sweat, so at first, it may feel like you've got a small towel stuffed under your armpits. I got used to that after wearing it only one time - it's no longer noticeable and feels just like a normal shirt. Since it absorbs the sweat in the armpit pad, I expected that it would also start to smell by the end of the day. Nope! While the pads do absorb sweat (and get wet) there are absolutely no bad orders that get trapped in the material. I would recommend getting more than one or washing after each use, however, since by the end of the day the armpits are very wet on the inside of the shirt and take a while to dry. The last thing you wanna do is put on the shirt again the next day and have wet armpits. Yes, its expensive for a t-shirt, and hopefully in the future, the company is able to reduce their costs as they grow and are able to offer these shirts at a more affordable price, however, I still think it's 100% worth it. I'm going to be buying 2 or 3 more in the next couple days since I love it so much and it works so well. BUY THIS SHIRT! That's all I've gotta say.

Muy buena camiseta,se nota que es de calidad,estupenda para el sudor.

Bonita. Excelente tela. SOLO ES UNA, cara pero linda.

Effective against sweat. Cotton feels good quality. We wash at 40 and tumble dry, didn’t shrink and lasts
