  • Does leaning back against your seat give you anxiety?

    Feeling beads of sweat roll down between your shoulder blades to the small of your back can lead to embarrassing pools of sweat on your shirt and the top of your pants.

    You shouldn’t have to bring extra shirts with you to work. You shouldn't have to slather your back with chemical antiperspirants. You shouldn’t have to drape a towel over your seat to hide pools of sweat.

    The back sweat proof undershirt from Ejis brings the same sweat blocking power of our sweat proof undershirts and expands it to cover your entire back.

    That’s over 600 square inches of coverage.

    No more sticking to seats.

    No more changing shirts in the toilet cubicle at work.

    No more hiding your back from clients and co-workers.

    Just a bone dry shirt, no matter how much you sweat.

  • 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.

    ENTIRE BACK PROTECTED with a waterproof layer that stops sweat from transferring to your shirt. With the sweat proof protection starting at the collar and travelling down the entire back as well as under each arm, the back sweat undershirt has you covered.

    STOP SHIRT SWEAT MARKS with Ejis waterproof undershirts that extend the life of your dress shirts by eliminating yellow stains caused by antiperspirants.

    SILVER COMBATS ODOR-CAUSING BACTERIA. Silver is permanently bound to the fibers of our sweat proof undershirts, to keep you fresher for longer.

    SUPER PREMIUM MICRO MODAL FABRIC 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 armpits, and your back, so sweat doesn’t you don’t want it.

    WHAT THIS UNDERSHIRT WON'T DO is make your sweat disappear. Unfortunately, we can’t stop sweat from happening. It may feel damp on your back and under your arms but sweat stains won't show on your shirt when you wear this powerful no sweat undershirt.

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.

    1st timer

    Great at keeping sweat from my outer shirt. They do get very clingy to my back when I try to take them off after work and sometimes golfing. Do wish the back went all the way across and not taper at the shoulder

    Almost perfect

    Would be better if the padding went further down the back but other than that, a happy purchase.

    Excellent customer service

    The first shirt I ordered was too small. Ejis sent me the new size quickly - no hassle at all. It’s a much better fit and quite comfortable.

    Runs small

    I’m a bit disappointed from the start. The shirt seems nice but I need to return it for a size larger. I always wear a standard large. Their large is skin tight. I hope the XL works.

    Life saver

    I am really impressed with this product, the undershirt is a great fit, and true to its word, it keeps the sweat on my back in. The sweat does not show up on my shirt. I have had problems with back sweats for a very long time, which has made life a misery especially in work settings. This undershirt is excellent and I will be making more purchases. Thank you Ejis.

    Ejis Sweat-Proof Shirts & Boxers are a Necessity!!!

    I have always been a warm guy, always sweating, always running hot and unable to control my body temperature. Dr's can't seem to figure me out so your shirts and boxer briefs are a business person's dream in my situation. Your products allow me to not "ONLY" wear black shorts/ jeans or black shirts to hide my sweat. I can rock salmon, blues, etc and it is amazing. I used to speak in front of large groups of business owners for work in warm environments and I would always be more concerned if I had butt sweat marks on my khakis or jeans than my presentations or speeches. EJIS is my go to going forward. Thank you for making these products. My only suggestion is making the front of the undershirts the same as the armpits and back, bc If I pick up my kid or fold my arms my shirt then does get wet from sweat on my chest. Thanks again

    Great

    Positively no sweat made it to my shirt, even in hot, humid Midtown on a June afternoon
