Extremely satisfied. I didn't think it was possible to keep my dress shirts as dry as these undershirts do. Thumbs way up! I'm ordering more very soon. – Joshua B.

Hi, I have been using the undershirts for some years. I have some medium and some small in micro modal and one in cotton. The medium (micro modal) size were a little too large at first, and have totally lost shape, the small ones also, they are more like pochhontas size now. The cotton models kept size, so I bought more of them.
Hi Jakup. Thank you for your feedback. I'm so happy you found an Ejis sweat proof undershirt that works best for you. Best, Gigi Ejis Customer Support
Padding is too bulky under the arms. But did save my outer shirt.
Hi Joe, Thank you for sharing your experience. We appreciate your feedback about the pads feeling too bulky. It may take some time to get used to the underarm protection. We are happy that your Ejis undershirt helps with sweat marks. Best, Gigi Ejis Customer Support
Positive experience👍�. No embarrassing pit stains
Hi Adam, Thank you for leaving a review. We are so happy to hear that you've had a positive experience with your Ejis undershirts. Best, Merrielle Ejis Customer Support
The fit is a little tighter than expected and the neck is a little too wide, which exposes the clavicle slightly
Finally something that really works!!!
Hi Louis, Thank you for leaving a review. We are so happy to hear that your Ejis undershirt has been working for you! Best, Merrielle Ejis Customer Support
I like to wear polo shirts that are on the nicer side. These prevent my sweat stains form seeping through to my polos. No longer have to worry about raising my arms in a meeting! MG

Been buying these shirts for years and absolutely love them. I have both fabrics and still cannot decide which one I like best. 10/10, at least!
Hi Michael, Thank you for your review & continued support of Ejis. We are so happy to hear that your Ejis undershirts are a 10/10! Best, Merrielle Ejis Customer Support
The neck portion of the crew neck shirt was much larger than a normal shirt which made it feel awkward while wearing it. I also ordered a size larger than my usual size knowing that these shirts usually have a “fitted” design. Even with a size larger, the shirt was much to tight to be comfortable. I’m 6 foot 5 inches, 230 pounds. I plan on going with a different brand from now on
Hi Joshua, Thank you for sharing your feedback. We appreciate the honest review about the undershirt not being 100% perfect for you. If you have not already, please reach out to us at support@ejisinc.com to see if you qualify for the First Product Guarantee. Best, Julie Ejis
I decided to finally try this t-shirt with a gray shirt I've wanted to wear to work, but always sweat through. I had an intense day with multiple presentations, and yet my gray shirt survived the day! I could wear it again without even washing it if I wanted.
Hi Heath, Thank you for sharing your experience. We are so happy you are pleased with your new Ejis sweat proof undershirt, and that it held up to the pressure of an intense day. Best, Julie Ejis
As a regular public speaker, I've been cautious of wearing colors other than black, and even then I'm worried if someone gives me a hug or gets too close. I tried my new crew t-shirt today and couldn't believe that my vest AND dress shirt were completely dry! I don't know how this voodoo works, but I'm so thankful it does!
Hi Heath, Thank you for leaving a review and for sharing your experience. We are so happy to hear you love your Ejis Crew Neck Cotton Sweat Proof Undershirt. Best, Wilbur Ejis Customer Support
I’ve been struggling with armpit sweat for years. I’ve had to throw out many good dress shirts due to stains and smell. My girlfriend found Ejis shirts and I ordered a week’s worth on my first order. They work great and I’ll be ordering them on the regular.

Hi Ron, Thank you for sharing your experience. We appreciate your feedback. Best, Wilbur, Ejis Customer Support
The Ejist sweat proof crew necks have become my go-to undershirt for almost every occasion. I love how effective they are and the confidence I can have knowing my sweat won’t show through my shirts. Try it and you won’t regret it. The fit takes getting used to but I think it needs to be a little bit snug to be effective.
