Works great, but a little awkward.
I wanted to add some photos of the shirt after working eight hours today moving furniture and wearing this sweatproof tee for the first time, but Amazon wants access to every photo and access to every part of your personal files, so I won’t upload the photos. The Ejis sweatproof tee worked well. You’ll see sweat on the under arm area on the inside of the T-shirt (against your pits) when you take it off, and you can feel the sweat building up under your arms, but it did NOT seep through the T-shirt into the outerwear. It doesn’t seep through at all. Long story short, if you’re just trying to stop sweat stains from appearing in the under armpits of your work clothes or anything else, this will work. The fit and the cut is very awkward, and the pad area under the arms. It’s kind it bunchy and weird at first. But for me, I just want to stop the massive visible sweat stains in the pits, and this does that, so I’m happy with the shirt. It makes me feel so much better and free to lift my arms without worry. This shirt is super long, meant to be tucked in and worn UNDER clothing you don’t want stained. I’ve seen people complaining about these shirts that you can’t wear them just as a T-shirt and that is not the point of these shirts. They are meant as UNDERSHIRT to block sweat from the outer clothes. Not be stylish to be worn just as a T-shirt out in public. There are pads under the arms and they’re NOT meant to be worn as just a T-shirt. It’s an undershirt to stop underarm sweat STAINS.

It's magic.
Ok, I was skeptical. I've tried many different things to stop the sweat from bleeding through my shirts. I have hyper-hidrosis and nothing has ever solved my problem. I would sometimes change shirts two or three times a day. I even pushed to have dress code changed at my place of business so I didn't have to wear dress shirts any more. Then I took a new job that required dress shirts and a sports coat. Needless to say this was not good for me. I never took off my sports coat to hide the sweat. Then I found the magic shirts. These things were golden. My first trial run with the shirt was on a day that required outdoor walking in the sports coat, 98 degrees, and 80% humidity. Yes, it was hot. I didn't trust this shirt yet so I left my coat on at lunch. After lunch I went to the restroom and took my coat off just to see. The outer shirt was dry as a bone. The undershirt does have pads in the pits that do feel a bit strange at first, but they quickly lose their awkwardness. Others can't tell you have it on, but you do know its there. It will absorb your sweat and you will feel it damp, but you have to trust it's doing its thing. It does run small, I mean small. I bought an XL to begin with and it fit more like a medium. I have since bought two more XXL and they are still snug, and fit more like a slightly oversized large. I will be keeping these in my arsenal for a long time.

No one else can see you sweating, but you will still feel it
UPDATE: I realized that the product page title for this product does not include 'slim fit' but the link that appears in my order history specifically states that it is slim fit. I do not know how the seller has let this slip. If I knew I was ordering slim fit I would have better rated this product and had more appropriate expectations. I do still believe that the overall length is not sufficient to keep it tucked in but I can't give the product less than four stars. The odor blocking technology is honestly very impressive. Since I only had one of these at the time and was waiting for the next shipment to arrive I was forced to wear this shirt more times than I would have liked. Even after sweating pretty heavily into it for multiple uses it still smelled more than acceptable to continue wearing. I wouldn't recommend it but it's good to know that it does control sweat odor extremely well. ------------------------------- I love that this shirt keeps me from sweating through whatever I am wearing over that, it is certainly effective in that regard. I found that the shirt was a bit tighter than I expected. I do not feel that I chose the wrong size, the length and sleeves and general cut seem to fit as intended but the shirt is a bit slim. The only issue I find with this is that the sleeve ride up into your armpit and trap any sweat that is there and there is no air circulation for it to dry out and I honestly think it might make me sweat more than usual because the waterproof layer traps heat in that area. So for me the final result is that it still feels as gross as any other shirt, if not more so, since the moisture stays but no one else can tell. I find the shirt generally really comfortable, my only gripe with it is when you are in an environment when you are sweating heavily and to me that is the point of this shirt. I will be buying more for those times I simply can't risk sweating through a shirt but I am not as in love with this shirt as I hoped to be.

This is a GREAT product, it works as advertised and as the other review say. I have bought both L and XL as you don't know how they will fit vs. other shirts. Both fit, of course the L is a bit more snug. I did have a hard time finding the care/ wash instructions but it was printed on a label on the second shirt I ordered. Hand wash, is the best I see... will buy more, works great for someone like me that has this issue my entire life.

It works perfectly. Especially in my location its common to sweat due to the heat, however these shirts made me more comfortable with not worrying about underarm sweat marks. Highly recommended

Ich leide schon immer unter starkem Schwitzen und konnte deshalb eigentlich nie Hemden tragen. Dies ist Dank dieses "Wunder-Shirt", nun endlich wieder möglich. Der Preis ist absolut angemessen und die Verarbeitung Top. Selbst nach 5-6 Stunden auf einer Hochzeit, hatte ich keinerlei sichtbaren Schweißflecken unter den Armen. Im Normalfall wäre dies sicher bereits nach 15min der Fall gewesen. Von mir gibt es eine klare Kaufempfehlung!! Ich habe des Unterhemd selber gekauft und es handelt sich um keinerlei Werbung. Wer zum starken Schwitzen neigt, sollte sich hier zu 100% bedienen. Ich werde mir zeitnah ein zusätzliches Hemd zu legen!

خامة ممتازة وتعزل الروائح كما في الوصف

Only recently discovering these anti sweat items for sweaty people like me. Absolutely fantastic, my only gripe is that it is a LOT longer than I expected. However it goes above and beyond what I hoped for!
