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.

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.
Love the product. I can wear it under a small-ish tee shirt and it does not show at all. Discrete and effective. Great product

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!

Hi Karolis, Thank you for leaving a review! I am so happy to hear that your Ejis undershirt is super! Have a great day, Merrielle Ejis Customer Support
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.
Hi Tim, Thank you for leaving a review! I apologize that your undershirts had a small hole in them after washing. We recommend washing them in cold water on a delicate cycle and hang drying. If you have anymore questions or concerns about this, please don't hesitate to reach out to us at firstname.lastname@example.org. I am so happy to hear that you love your undershirts! Have a great day, Merrielle Ejis Customer Support
