Review: This t-shirt saved my wardrobe - $30 for a t-shirt? Are you kidding? This better be worth it. Verdict: It’s worth every penny. I sweat…a lot. I’ve ruined several very nice dress shirts as a result with sweat and deodorant stains in the armpits. Thanks to these t-shirts, my dress shirts are safe again. I’ve been wearing them for about 5 months now, and not a drop of sweat has leaked through to my dress shirts. That includes wearing them in 95 degree heat and humidity. I may be sweating on the outside, but my dress shirts stay bone dry. Plus, they’re comfortable. Yes, the armpits are bulkier because of the multiple layers, but I got used to it very quickly, and now I don’t even notice it. I also like that they have a trim fit to the body, but also have enough give for those of us who have put on a few pounds. There are a few minor negatives. I wish the V neck was a little deeper - with a few of my shirts, you can see the t-shirt collar poking out if I leave the collar unbuttoned. It’s longer than most other t-shirts. In a way, that’s good - less chance that it will come untucked and ride up - but if you’re shorter than average like me, it could get annoying (personally, it doesn’t bother me). And then there’s the price - but if a $30 t-shirt can stop me from ruining a $100 dress shirt, then that’s a win. Five stars - highly recommend.
Review: I wish I would have discovered these years ago! - As many people who’ve tried Ejis would likely say, I’m upset I didn’t learn about these sooner! Talk about instant confidence boost! These things really do their job, and they do it extremely well. I’ve soaked through my dress shirts every day for years, to the point where I’d change undershirts several times a day and either change or dry my dress shirt midday. I couldn’t believe how well these shirts have worked. Not only have they prevented sweat from reaching my outer shirt, I’ve noticed that I have absolutely zero odor at the end of the day. None. These have exceeded my expectations so far, and I would highly recommend. I’m curious to see how these hold up long-term. They seem very well-constructed and made to last. The benefits definitely outweigh the cost. Don’t let the (very high) price tag deter you, these are worth the investment. I also love the comfy fabric as well as the fit (see photo). They’re made to be form-fitting; this helps them do their job. I’m 6’2, approx 220 lbs, 41” chest, 34” waist and typically wear L shirts. I followed the size chart, ordered L and am very happy. tl;dr Buy these shirts now if you have sweaty pits. Ejis= huge confidence boost. You deserve it.

## Questions & Answers

**Q: What makes Ejis undershirts' sweat proof protection unique compared to other sweat proof undershirts?**
A: Ejis' sweat proof pad is made of one piece of material. Other sweat proof undershirts have a seam running through the pad. No seam means less chance of leakage. Each undershirt also has 140+ square inches of class-leading protection.

**Q: How do your undershirts fight against odor?**
A: The fabric used for Ejis undershirts is treated with silver technology by Silvadur to provide enhanced odor protection.

**Q: Can I wear antiperspirant or deodorant while wearing an Ejis undershirt?**
A: Yes, you can use antiperspirant and deodorant with an Ejis sweat proof undershirt. Antiperspirant won't impact how well the undershirt stops sweat. The undershirt will even stop yellow stains from forming on your dress shirts!

**Q: Can I wear an Ejis undershirt even if I don’t sweat excessively?**
A: Of course! Ejis sweat proof undershirts stop any amount of sweat from reaching your shirt. They also stop yellow antiperspirant stains from ruining your shirts and control embarrassing odors.

**Q: How do I wash and dry an Ejis undershirt without damaging it?**
A: Good new! Ejis undershirts are designed to be machine washed and dried just like your other clothes. Turn inside out, wash with cold or warm water, and dry on a low setting. Avoid high temperatures, bleach, and vinegar so your undershirt lasts.

### ⭐⭐⭐⭐⭐ Amazing
*by S***D on September 5, 2023*

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.
