    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.

    Why Ejis?

    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.

Frequently Asked Questions

What does sweat proof mean?

Our sweat proof undershirts and boxer briefs are engineered to prevent sweat stains. Can we stop you from sweating? Heck no! But we can keep sweat marks from appearing on the armpit of your dress shirts and the seat of your pants.

What if it doesn’t work?

You get a full 45 days from purchase to put your first undershirt to the test to make sure it really works for you just like it does for tens of thousands of other men. If you feel it’s not right for you just let us know and we’ll give you a refund. Valid for single units only. Multi-packs are eligible for our Satisfaction Guarantee 45-day Return Policy. See the FAQ more details.

How does a silver-infused undershirt fight odor?

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.

Where do these shirts get their sweat-fighting superpowers?

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.

    7 Day Review

    I have tried this under shirts a couple of times now. Works perfectly. Very comfortable to wear. The non-armpit parts are thin, breathable and dries quickly when washed. Cannot comment on long term quality as I’ve only had it for a week but looks promising. Very difficult to fault this item.

    Exactly what I needed. It’s not too heavy and does the job. Thanks for the shirt.

    No sweat through.

    It was a little weird feeling in the underarm area at first but as the day went on it was barely noticeable. Waited for the second wear to review, and it was more comfortable than the first! Shrinkage was minimal. I like the length as I'm 6'3" and they are plenty long to stay tucked all day.
