Amazing product - perfect fit and feel of fabric. 100% sweat proof. Love it would recommend strongly!! Only complaint is the easy pilling of the fabric after being on a gentle dry cycle - which it needs to go on because it will not dry otherwise.
For the first time, I can go to work wearing light colours and know there won’t be sweat in my back that will be visible. My whole back sweats, and it used to stop me from excelling at work. Now I have confidence, it’s changed my life and it’s the best thing I have ever bought. It would be great if this cover the chest as well, all round protection, but it’s not that big deal, as my back and arm pits. Thank you Ejis, you have really helped me get on with life, I can’t thank you enough

Great at keeping sweat from my outer shirt. They do get very clingy to my back when I try to take them off after work and sometimes golfing. Do wish the back went all the way across and not taper at the shoulder

Would be better if the padding went further down the back but other than that, a happy purchase.

The first shirt I ordered was too small. Ejis sent me the new size quickly - no hassle at all. It’s a much better fit and quite comfortable.
I’m a bit disappointed from the start. The shirt seems nice but I need to return it for a size larger. I always wear a standard large. Their large is skin tight. I hope the XL works.
Hi Patrick, Thank you for sharing your feedback. I am sorry to hear that your undershirt didn't fit the first time. I hope that the XL undershirt is a perfect fit! Please reach out to us at support@ejisinc.com if there is anything more we can do! Have a great day, Merrielle Ejis Customer Support

I am really impressed with this product, the undershirt is a great fit, and true to its word, it keeps the sweat on my back in. The sweat does not show up on my shirt. I have had problems with back sweats for a very long time, which has made life a misery especially in work settings. This undershirt is excellent and I will be making more purchases. Thank you Ejis.

I have always been a warm guy, always sweating, always running hot and unable to control my body temperature. Dr's can't seem to figure me out so your shirts and boxer briefs are a business person's dream in my situation. Your products allow me to not "ONLY" wear black shorts/ jeans or black shirts to hide my sweat. I can rock salmon, blues, etc and it is amazing. I used to speak in front of large groups of business owners for work in warm environments and I would always be more concerned if I had butt sweat marks on my khakis or jeans than my presentations or speeches. EJIS is my go to going forward. Thank you for making these products. My only suggestion is making the front of the undershirts the same as the armpits and back, bc If I pick up my kid or fold my arms my shirt then does get wet from sweat on my chest. Thanks again

Positively no sweat made it to my shirt, even in hot, humid Midtown on a June afternoon
Hi Mark, Thank you for leaving a review. I am so happy to hear that your Ejis undershirt kept you dry all afternoon! Have a great day, Merrielle Ejis Customer Support
In my experience, I start off my day by seeing a patient and then running to the restroom to wipe down my back that's drenched in sweat and changing undershirts. I usually have to repeat this process multiple times a day. It's embarrassing and really messes with your mental health. I saw these recommended on reddit no less, so I tried a shirt / boxer combination because it's all I could afford. I tried it out twice with light colored scrubs and it was fantastic! no dripping back/stains or leg/butt sweat stains. I'm hoping I can afford another couple pairs in the future as I have to wash them multiple times a week to re-use.

As a sufferer of hyperhidrosis where my main problem is my mid-to-lower back, I have tried everything I could think of to hide the pools of sweat that would gather near the small of my back. Prescription strength antiperspirants, prescription pills, dri-fit & moisture-wicking undershirts - nothing could stop the embarrassing sweat marks from showing all over my back. It got to the point where I could only wear dark colored shirts, would need to carry 1-2 undershirts with me wherever I went, and would find any excuse to be the last person to leave the room so not to show my back sweat marks. While I have had success with Ejis undershirts to relieve the stress of worrying about underarm sweat but still could not contain my back sweat. I am so happy that Ejis developed the Back & Underarm Sweat Proof shirt! The first time I tested out this shirt I put it to the test - a baby blue dress shirt under a suit coat on a hot day! Throughout the day wearing the shirt, I could feel my back sweating and pooling near the small of my back. Thinking there was no way I didn't sweat through another "sweat-proof" shirt, I went to check and was in pure disbelief when I looked in a mirror to find that not a single drop of sweat was showing on my dress shirt! Normally I would keep my dark colored suit coat on the entire day no matter the temperature just to hide the sweat marks, but after lifting both arms and a couple of twirls in the mirror, with not a drop of sweat to be seen, I ditched the jacket and confidentiality went about my day without a second thought of showing embarrassing sweat marks! I highly recommend the Ejis Back & Underarm Sweat Proof shirt to anyone who suffers from underarm or back sweat, for anyone who wants a little more protection for those high-activity or warm days, or for anyone who likes a little piece of mind knowing that this undershirt has you completely covered! I cannot thank Ejis enough!

I've needed this full back protection undershirt for the longest time. It arrived and is simply incredible to wear! I never have to worry about having huge sweat patches across my back. The shirt protects the ENTIRE back as well as the underarms. It's super comfortable as it's made from the same fabric as the other EJis undershirts I have. Love this beyond words. Worth every penny.
