Tired of undershirts that can’t keep up? Ejis undershirts don’t show sweat, and keep you cool in the heat – whether that’s a hot day or the pressure of suiting up to close a big deal.
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."
Our crew neck sweat proof undershirts feature a comfortable micro modal fabric that absorbs sweat and keeps dress shirts dry. They’re comfortable, they fit well, and they do their job so you can confidently do yours. The crew neckline is perfect under a suit and tie. Now that we think about it, this undershirt is as successful as you are – you’ll make a powerful partnership.
In our Ejis crew neck micro modal sweat proof undershirt, luxuriously soft micro modal is permanently fused with real silver to fight odor in a flattering slim fit cut. An impenetrable sweat proof barrier under each arm stops sweat marks. Added length and stretch keeps your undershirt tucked in.
All Ejis sweat proof undershirts are 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.
Need a different style? Check out our V-Neck and Deep-V options.
LARGE ONE-PIECE WATERPROOF LAYER – Stops sweat in its tracks – that is, sweat won’t transfer 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.
BACTERIA-FIGHTING SILVER TO COMBAT ODOR – Silver is permanently bound to the fibers of each sweat proof undershirt, which keeps you fresher longer. It also helps to regulate your body temperature by pulling heat away from the body when you're hot.
SUPER PREMIUM MICRO MODAL FABRIC – Twice as soft 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.
ADDED LENGTH TO KEEP YOU TUCKED IN – 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 no sweat undershirt.

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 have worn the shirt once so far and was pleasantly surprised that it 100% worked. I'm very impressed and will definitely purchase more in the future.
