  • Our deep v-neck undershirt is the most versatile sweat proof shirt you’ll ever own. The deep v-neck is designed to keep your undershirt invisible when you wear a work uniform or a dress shirt without a tie, yet it’s also perfect for casual wear on the weekend. Whether you’re in the office or at the bar, this deep v-neck shirt is an essential addition to any man’s sweat proof clothing collection.

    Unlike most deep v undershirts, Ejis slim fit shirts are extra long to stay tucked in. We built them this way by design to keep the sweat-absorbing pad snug against your armpit where it can do its job.

    Our sweat proof men’s shirts won’t eliminate sweat, but they’ll prevent sweat stains and fight odor. In fact, we guarantee the sweat-absorbing areas will keep 100% of your sweat from reaching your dress shirts or your money back.

    How is the cotton deep v-neck undershirt different from the micro modal undershirt?

    Micro modal fabrics have powerful sweat-absorbing and sweat-blocking properties. Cotton is lightweight and breathable. We combined them to create the ultimate sweat-resistant undershirt. Our deep v-neck undershirt is made with lightweight, premium cotton and features a micro modal sweat blocking pad in the armpit area to keep your shirts clean and dry.

  • 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 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 alone, which means our deep v-neck cotton undershirt 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.

    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 v-neck shirt.

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.

    Worth It

    Good but not as good as the Micro Modal one but still definitely worth it.

    Great product

    Great product, I have bought other brands and in all honesty none of them are anywhere near the quality of this products. I buy 5 of these every 4 months.

    Sizing is liberal

    This shirt performs well and is comfortable to wear. Hand wash is simple allow full 24 hour drying time. Sizing is liberal. If you are between two sizes, go for the smaller size.

    Never ruin a shirt again!

    Love it. I prefer the regular V-neck but as far as stopping the sweat it gets an A++.

    Product really works!

    This was my second time buying these undershirts because they really work. I have an extremely high metabolism and train regularly therefore I feel like I’m constantly sweating. I was looking for an undershirt that would keep sweat marks off my shirts. These shirts did just that, I now I can wear every shirt in my closet again, not just the dark colors. If you have this same issue buy these undershirts. They just work!

    Love the shirts; hole after washing

    I’m a repeat customer and love the shirts, but my last two shirts both have a small nick/hole in them after one wash. (Delicates, no bleach, inside out). Not sure why this happened, but disappointed since they cost a pretty penny to buy. Still love the shirts. Just wish they were in better condition after washing.

    It does what it says it is going to do

    This is a great undershirt that stops sweat in it's tracks. I wash my shirts less, it stops odor and fits great! I am definitely going to buy a few more of these and get rid of my old undershirts.
