comfortable, and not worrying about my sweat all the ...
This shirt is a life saver. I've struggled with sweating ever since I can remember. It got to the point I was bringing a spare under shirt and spare button down to work almost everyday. If I had a meeting or presentation I was always changing shirts before or after. I own two of every dress shirt just so that people won't notice if I change my shirt mid day at lunch due to sweating. Gone are those days. I just spent a week on the road, meeting with customers, execs, teaching classes, all sorts of things that up my anxiety and make me go through shirts. This shirt really is sweat proof. I did the unthinkable. I wore the same shirt on a 16hr day. Never in my wildest dreams did I think I'd be able to do that. These shirts have changed my life, I'm more confident, comfortable, and not worrying about my sweat all the time. Side perk, if you buy them a tad small, they can help keep your belly in. :) I ordered the small, and it works great. Good length to tuck in, nice and tight in the pits so that nothing transfers to the overshirt. Worth the price alone just to keep from ruining dress shirts with permanent pit stains, let alone laundry/dry cleaning bills. But honestly, the confidence and freedom from worrying is priceless. I own 5 shirts now, one for each work day.

Great Product. Kept my dress shirt sweat free!
1) Best undershirt I’ve ever owned! 2) onto the review. In short, I’m extremely pleased with this shirt and it does exactly as advertised and keeps the sweat on the interior of the undershirt instead of showing on the outside of my dress shirt. I was looking for a way to prevent sweat from showing through my dress shirts as it is quite embarrassing to me to not be able to lift my arms up (I know it’s natural, I just sweat a lot). I came across this product along with another. In XL this one was available for prime so I selected it and I am happy I did. It arrived early this morning and so I decided to try it out in full force and put on one of my shirts that shows the most sweat. First thing I noticed out of the package was how soft the shirt was. It is a light thin material, except in the pit area which is a much denser material. After putting it on I immediately noticed it was cooler than my other undershirts. I did find that it was pretty tight for an XL on me. Typically it doesn’t take me long to have some sort of mark in the underarm (within 30min or so) and I didn’t see a single mark through my entire work day. I walked in the sun to get a sweat up and still nothing. When I got home and rolled around on the ground playing with my kids, I then noticed a slight sweat mark near the edge of where the denser pit area is. That said it was very slight. I thought that maybe I hadn’t sweat much was the reason for no mark, but pulled the shirt off and found that I had it was just well contained. Thank you for a great product, I have to go order more. Cheers!

Fit for the courtroom and the dance floor
As a ballroom dancer, I need clothing that performs in athletic circumstances yet maintains formal style. The Ejis undershirt lives up to the challenge! I ordered it for a Christmas dance event which involved three hours of social dancing, and towards the end I had a quickstep performance. This involved fast steps, kicks, tricks, running, jumping, and lifting my dance partner on multiple occasions. My body runs significantly warmer than the average person, I sweat a lot, and I put this undershirt through everything. Yet despite the warmth of vest and tie, there was no sign of sweat on my white dress shirt, thanks to the Ejis undershirt. The construction of the garment is marvelous. It fits closely without bunching or riding uncomfortably under the arms, leaving the fortunate wearer feeling ordered but not stifled. Thanks to the cotton-spandex blend, it breathes much better than a standard cotton undershirt, making it feel more like a gym shirt or cycling shirt. The unique fabric is contoured, soft, and cool. Taking it out of the packaging, this undershirt may appear bulky at first because of the additional material in the armpits, but slide it on and it transforms into the essence of comfort. How this shirt manages to be both light and free for the wearer and yet impassable for sweat is a remarkable feat. As both a ballroom dancer and an attorney, I need to look and feel my best in front of a crowd in order to perform to the standards of elegance I demand in both settings. I will wear Ejis in the courtroom and on the dance floor now. Ejis is "wearable confidence" indeed, and should become the trusted assistant to any discerning gentleman.

Comfortable, Discreet, and Truly Sweat-Proof
📝 Quick Review This undershirt is soft, well-fitted, and effective at preventing sweat from showing through, making it perfect for work, special events, or hot weather. The V-neck design stays hidden under dress shirts, and the fabric feels lightweight yet durable. They are on the expensive side, but the performance and comfort help justify the price. 👕 Why It Stands Out Built-in sweat barrier under the arms for reliable protection Comfortable stretch fabric that moves with you Discreet V-neck stays out of sight under most collars Breathable material keeps you cool while staying dry ✅ Final Thoughts An excellent investment for confidence and comfort in any situation where you want to look sharp without worrying about sweat marks. While pricey, the quality makes them worth considering for regular or special-occasion wear.

Diaper in the armpits, but it actually works!
I've been a skeptic of this idea for months now, but decided to take the plunge and try one of these shirts out. It worked even better than I had expected! I am such a sweaty beast that I will often sweat through my undershirt, soaking the armpits of my dress shirt, before I even make it out of the house, IN THE WINTER. We keep our thermostat on 60º F in winter, so there's no reason I should sweat this much. The only thing that has ever helped, other than this shirt, is a 10 day juice fast. Since I cannot maintain a life without solid food, I had to seek out other ways to keep from showing up to work with a visible sprinkler system in my armpits. While I still sweat like an Elvis on the toilet, this shirt kept it from showing! After an entire day of intense sales-related anxiety, I never showed a drop. My regular customers all assumed that I had gotten some sort of experimental surgery! I was able to hug short people without my armpits pissing all over their shoulders! Ejis, I might never remember your ridiculous name, but I will tell all of my fat sweaty friends about this shirt, that I found on Amazon, with the mega-heavyflow-maxipads sewn into the armpits, and how they actually keep you from looking like an imbecile. No, I can't remember the name. But I don't think there's anyone else doing this, so just get on your 'puter and search for the sweat proof shirts. You'll find it. My only complaints is that it kinda feels like you're wearing a diaper under your arms, especially by the end of the day. Until some other solution becomes available, Efgi'a is the way to go! The only thing I would change is to not sweat at all, but you can only work one miracle at a time, so this shirt will do until then. Thanks Ije's!

I Get to Be Normal
Out of all the body dysfunctions I could have, Hyperhidrosis is not bad, but it sure does mess with your confidence. Admittedly skeptical when purchasing, but I have been this way for years and tried it all. Prescription antiperspirants and medication never did the trick, after years of being self conscious to lift my arm up in public, I was willing to give a shirt a try (It was this or Botox injections in the armpit). I assumed it would feel bulky, would make me hotter causing more sweat, or just in general make me self conscious that people could notice; all were wrong. This shirt fits better than expected, blocks sweat better than expected (ZERO perspiration shows), and is almost completely unnoticeable. The Ejis shirt has been a game changer for me getting ready for work in the morning and not having to worry about sweat marks appearing before I have even arrived at work. Not having to worry about buying clothes that are less obvious when wet. All around a better life experience. I have found I actually sweat less in general as I am not constantly thinking about my sweating. The price point is higher than expected, but $35 for daily peace of mind. It's worth it. Hope the same can happen for you. Justin

TL;DR It works phenomenally.
Since adolescence, I have had an issue. I sweat EXCESSIVELY under my armpits. I'm not even an overly heavy guy or anything. I just sweat under my armpits excessively. Everything I've done to make it stop has failed. Prescription strength antiperspirant, diet change, napkins under my armpits; you name it, I've probably tried it. So, I've just learned to live with it. I wear shirts that hide it to a degree, but it's still visible. I wear over shirts, but eventually I sweat through to them. I wear hoodies and sweaters over said over shirt, but, again, eventually, not even a half way through my day, I'll sweat through to them. It's stained almost every single shirt I own. I've had to throw out and re-buy my entire work-shirt catalog more times that I care to admit. Last week, I bought this shirt. Let me just say this one thing. It works. I'm not joking when I tell you it's changed my life INSTANTLY. Zero moisture has soaked through. None. Nothing. For the first time since my teen years, I feel like a normal person and not a freak. It's something I cannot describe. I've washed it every night just so that I can wear it every day. I plan on buying more. This is seriously the best purchase I've ever made. My only regret with this product is not finding it sooner. If the people who make this product are reading this, just know that I thank you from the bottom of my heart. I hope anyone who has similar issues to me finds this, because it has changed my life.

These undershirts have absolutely changed my life.
Let me start this review by saying these undershirts have absolutely changed my life. I am naturally hot-blooded, or whatever you want to call it, and have decided I must always be at least 20 degrees warmer than anyone else currently in the room. Add to that the heavy amount of coffee I consume in the mornings at work, plus the stimulant medicine I sometimes take which can cause a significant increase in underarm/back perspiration, and you have a recipe for disaster. The sweating was inevitable, and as such I would always plan my shirt purchases around whether or not I thought perspiration would be visible. As you can imagine, this limited my selection by a huge amount. I'm sure many who are reading this understand that situation. In the time I have owned these, wearing one every single day during the work week, I have never ONCE had visible perspiration on any shirt I have owned, either under my arms or on my back. I honestly could not believe it the first day I wore one of these. Something I had struggled with daily since I was a teenager was magically solved and entirely not an issue anymore. The shirt itself is a highly stretchy, breathable fabric which is comfortable and durable. Unlike similar brands, this undershirt is made of a sweat-wicking fabric, which protects back-perspiration from being visible as well. Another benefit of this material is that it is thin and does not show up under dress shirts, even when wearing very thin, slim-fitting dress shirts. This is also true for the "sweat pads" under the arm. I also love how long they are, as this makes it easy to tuck them in. The perspiration was something I was constantly aware of, each and every day, but since finding this product I am able to wear any color/fit/type of shirt I want, whenever I want, how I want. If these shirts were discontinued, I would buy 10 more, and if they were only available for $100, I'd still buy it. Seriously. That's how amazing these are. I originally purchased one of these undershirt about 9 months ago, and have purchased 5 more since then. If you are looking at this product, and are worried about the price, just buy it. Hopefully they change your life in as positive a way as they have changed mine.

Anti Schweiss Hemden
Absolutes Top Produkt für alle, die unter Hyperhidrose / übermäßigem Schwitzen leiden. Ich kann seit diesen Shirts endlich mal Farben tragen und nicht nur weiße Oberteile. Man sieht auch bei übermäßigem Schwitzen absolut keine Schweissränder. Ich bin mehr als begeistert.

Great
Product came quick. Fits perfect, is comfortable and can't see under work shirt. Absorbs fantastically. I'll buy more soon as I got 2 to see if they were good.

Camisa interior de gran calidad
Muy buen producto, true to size, la idea es que queden justas mas no aprietan por el material lo suficientemente elástico. No son económicas pero valen lo que cuestan. Recomendadas
