  • When you need to look your best in a suit and tie, wear a sweat proof cotton crew neck undershirt from Ejis. Our powerful sweat stain prevention capabilities and odor crushing technology will leave your dress shirts bone dry and leave you smelling great.

    Stop throwing out perfectly good dress shirts because of ugly yellow stains caused by antiperspirants. Your days of being “the sweaty guy” are now behind you.

    How is the sweat proof cotton shirt different from the micro modal undershirt?

    To keep you looking dry we used micro modal in the pad to deliver the same sweat absorbing and blocking performance as our full micro modal sweat blocking undershirts and paired it with lightweight, premium 100% combed cotton for the body of the shirt.

  • 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 anti-sweat cotton 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 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 alone, which means our cotton sweat proof shirt has the exact same sweat blocking performance as our micro modal undershirts.

    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 – upgrade to an extra-long sweat proof undershirt.

    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 crewneck.

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.

    Surprised

    Having no to little sense of smell the presence of sweat undermines my confidence and stresses me out, leading to (you guessed it) more sweat. I tried the undershirt, somewhat sceptically, and rather than caking on an anti perspirent stick just plumped for a light body spray. Normally I would look like a reservoir had burst under each armpit so I was happy to report a dry shirt (and undershirt interestingly) and no one backing away (social distancing excepted) Thanks Ejis

    Never leave home without my Ejis

    I’ve bought probably 25+ of these over the last 2 years. Definitely a game changer and I wear one pretty much every day.

    Finally Can Stop Worrying

    I love it. I wear a suit every day in a retail environment, and I’m running around the store all day, even unloading trailers. You could see sweat stains in the armpit area of my suit. I was thinking about it every couple of minutes all day long. I wore this shirt the other day, and wow. I was nervous all the first time I wore it because I could feel I was sweating profusely, but every time I checked under my jacket, my dress shirt was completely dry! So happy I took a chance on this shirt. I wore it again today, and only thought about it a few times during my shift, which is a minor miracle. I could concentrate on my job instead of my potential embarrassment.
