Good undershirt for men.
Perfect for my use. I ordered large and fits now, but next order will be x-large as I'm in a wheelchair and don't exercise as much anymore.

Must have!
Originally I bought two shirts (one Ejis and one Thompson Tee) for my husband to just try it out and compare. He was skeptical at first but he instantly fell in love with the Ejis’ one. It fits like a glove, doesn’t bulk under clothes and it’s definitely long enough to tuck it in once and for all. Finally, the one piece pads make a huge difference and by far exceeded our expectations. For my husband the choice was obvious- Ejis. He didn’t like the Thompson Tee as much. But before making second order we decided to wait and see how it will behave after the wash, we followed the washing instructions and- it came out of the dryer just like new. Next step- we ordered black one. No stains, just perfect! An addition of silver fibers makes a big difference too, and it was my professional choice to go with it (I’m a microbiologist) - no smell as it prevents bacteria to grow. Of course it still has to be changed daily, as any underwear :), don’t get me wrong. Within short period I ordered in total 8 shirts, whites, black ones, crew necks, V-necks. I admit it’s not cheap, but I feel it is worth the money for the extra boost of confidence it gave to my husband (making my life easier too as we can go out more without him being unhappy). All together- I highly recommend it.

YES
My boyfriend wears professional attire all day for presentations, meetings, etc but he sweats like crazy. Like. Crazy. We tried the antiperspirant applications but nothing seemed to work. I bought one for the poor lad and it worked. IT WORKED. major confidence boost for him. No stain, no embarrassing drench- he was dry and clean all day. Since he’s bought about 5 or 6 more. They are costly, but they are worth it. They don’t look out of place, they fit well and they work.

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.

Prevents armpit stains even when sweating heavy
This is the fourth of such product, second of ejis I got. Continue to be a life saver. Fits great, feels great and most of all prevents armpit stains. I'm the heaviest sweater I know and living in a hot and humid area. And it works. Still wish these were cheaper though.

best sweat proof undershirt
This is great, exactly what I needed as I sweat a lot during the day. High quality, thin, and lasts much longer than the other brand of sweat proof undershirt I was using before. I hope they add more colors (gray, etc.)

Lasted about half of an active day
Not worth the price. Thought it work better because I'm a female. Oh well

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!

Das shirt erfüllt über einen längeren Zeitraum vollumfänglich seine Funktion und alle Gerüche gehen beim Waschen problemlos raus. Im Vergleich zu anderen herstellen ein gutes Produkt.

Excellent under shirt. So comfortable to wear and will be getting more. Never through about wearing one before but read the reviews and though I’d give it a go. Well worth it.
