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."

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.
Works wonders, would definitely recommend.

Love the shirts!
This was the first time I've tried the Micro Model V-Neck Undershirt. I've always suffered from ruined shirts from "yellow" underarm stains. Your product works well for me. I'll gladly purchase again. My only suggestion is to also offer a beige color. I currently a couple of beige ones from another company.
The first time I tried my grey sweat proof undershirt from Ejis was at the two and a half hour Easter vigil mass I went too. Normally when I wear a suit coat, I DRIIPPP sweat through my under-arms and back. But not THIS time. I was COMPLETELY DRY. Never happened before and was so pleased. I really wish I had gotten this shirt LONG ago. Before you buy an undershirt from Ejis, don't buy a smaller size then a t shirt you usually wear, just buy the same size of shirt you always wear. It will still fit perfectly. My mistake was buying a smaller size and was too tight, but the next size fit perfectly. Also, Julie from customer service was REALLY helpful. She was really kind with helping me exchange my first small shirt for a bigger size. She was also VERY polite! She deserve a raise! :)
Hi Anthony, Thank you for sharing your experience with Ejis. I am so happy to hear that your Ejis undershirt kept you dry throughout the entire holiday! We appreciate your kind words about Julie and her customer service, she's awesome! Have a great day, Merrielle Ejis Customer Support
Really great product. My issue is sweating down my lower back and sides. I wish you could make a shirt with the same layers of protection that the arm pits have.
Hi Brandon, Thank you for leaving a review. I am so happy to hear that you really like your Ejis undershirt. We appreciate your feedback and I will send it on to our product development team.
