Men Love the Ejis Sweat Proof Undershirt
Thousands of satisfied customers have discovered “Wearable Confidence” in an Ejis shirt. Some of our most loyal customers are wives who buy our sweat proof shirts for their husbands. Read our reviews below to see what men everywhere are saying about Ejis.
LARGE ONE-PIECE WATERPROOF LAYER stops sweat from transferring to your shirt. Think of it as your never-fail backup to antiperspirant deodorant, durable enough to be washed over and over and chemical free.
SILVER COMBATS ODOR-CAUSING BACTERIA. Silver is permanently bound to the fibers of our sweat proof undershirts, which keeps you fresher longer. It also helps to regulate your body temperature by pulling heat away from the body when you're hot and keeping you warmer when you're cold.
SUPER PREMIUM MICRO MODAL FABRIC IN THE PAD is 2x softer and 50% more water-absorbent than cotton. With 5% Spandex to add stretch, it will possibly be the most comfortable men's undershirt you've ever worn.
STAYS TUCKED IN with added length. The slim fit design keeps the protective area snugly up against your armpit, where it belongs. Stop settling for slopping, disheveled t-shirts under your dress shirts.
WHAT THIS UNDERSHIRT WON'T DO is make your sweat disappear. Unfortunately, we can’t stop sweat from happening. It may feel damp under your arms but sweat stains won't show on your shirt when you wear this powerful sweat proof undershirt.
We founded Ejis based on the belief we could make you feel more confident by solving two of your most embarrassing problems, sweat marks and odor. We've woven intelligent design, world class functionality and unrivaled comfort into our undershirts to give you what we call "Wearable Confidence."
The Ejis sweat proof undershirts were engineered from the ground up specifically for the exceptional man who wants an unfailing, discreet solution to sweat marks and bad odor. Join the thousands of men who are now able to wear what they want because of their Ejis undershirts.

Bacteria cause odor, and silver has anti-odor properties. We infuse silver particles into our fabrics to help fight that odor-causing bacteria. Our odor-resistant undershirts are scientifically engineered to keep your shirts smelling fresh. Each of our anti-odor undershirts includes this powerful technology, as do our odor-fighting socks and sweat-proof underwear.
It might look like just an undershirt, but there’s a lot of technology behind our design. We begin with a soft, moisture-wicking micro modal pad fused with silver to fight odor-causing bacteria. We then add a durable waterproof layer to help defend your dress shirt from sweat, and finish with a super comfortable outer layer. The result is an undershirt with a sweat-proof barrier that keeps sweat from showing through to your dress shirt, and stops sweat marks or deodorant marks.
I’ve been purchasing these and the deep v-necks for a few years now. Completely worth it. I work long hours in and needed a way to protect my dress shirt and sweaters from myself. These do just that.
Hi Jae, Thank you for your review. I am so happy to hear that your Ejis undershirts have been completely worth the purchase and are protecting your dress shirt daily! Have a great day, Merrielle Ejis Customer Support

Does exactly what it’s supposed to do Haven’t had an issue with sweat marks under my armpits at temperatures up to ~90°F. I haven’t worn it at temperatures above ~90°F, but would expect it perform just as well.
Hi Michael, Thank you for leaving a review. I am so happy to hear that your Ejis products are working exactly as you need them to! Have a great day, Merrielle Ejis Customer Support
Let me start by saying, I am not the person to write reviews. However, all of these products have been LIFE changing for me. I suffer from hyperhidrosis and have never been able or confident enough to wear light colored shirts. With these shirts, I now have the confidence knowing sweat will not show through on my shirt. These products work very well! If you are hesitant about buying, don’t be! You will not regret it! I will be a lifetime customer.

Hi Walter, Thank you for leaving a review! I am so happy to hear that your Ejis undershirts are a life saver for you. We appreciate you being a valued Ejis customer. Have a great day, Merrielle Ejis Customer Support
I was not expecting these clothes to perform so well. They really are quality material and design and construction. HOWEVER... I was still able to sweat enough to have little stain on my arm pits. This could be because the material got shifted or something. Also, when you have sweat crazy heavy for hours, it feels like you are carrying around two wet heavy "full of water" rags under your pits. Ultimately, my sweat problem is just ridiculous and this product is not perfect, but close to it.
Hi Jammi, Thank you for sharing your experience. I'm sorry that your Ejis undershirts are not working perfectly for you. Since everyone sweats differently, what works for some will not work for others. Unfortunately, as with any absorbent material, our sweat pads have a saturation point. When they reach their saturation point, they either need to be changed or risk leaking. We have several tips on how to manage sweat in our blog that may be helpful: https://www.ejisinc.com/blogs/news. If sweating through your Ejis sweat proof undershirts is a recent development, then it's possible that you're sweating more than usual or that the sweat proof layer was damaged during laundering. Damage can happen if you launder your sweat proof products with bleach, vinegar, high heat or dry cleaning. I hope this information is helpful. Please let me know if there is anything else I can do for you. Best, Merrielle Ejis Customer Support
Does what it is supposed to do. Quite baggy at the underarm area though, so tighter fit shirts look a bit off.
Hi Graham, Thank you for sharing your feedback. I apologize that the undershirt did not fit perfectly. If you would like to exchange for a smaller size, please feel free to reach out to us via firstname.lastname@example.org. Have a great day, Merrielle Ejis Customer Support
Nice shirt really really really really really really really really really really really really really comfy!
Hi Jaylon, Thank you for leaving a review. I am so happy to hear that your Ejis undershirt is keeping you comfy! Have a great day, Merrielle Ejis Customer Support
