A simple v-neck undershirt should be a staple of every man’s wardrobe. If you wear a button-up shirt without a tie, you need a v-neck to keep the undershirt out of view. And unless you enjoy sweat stains on your dress shirts, a sweat proof v-neck is an absolute essential.
We’re like most guys – we hate sweat, and we hate sweat stains. Ejis v-neck sweat proof cotton shirts are scientifically engineered to resist sweat stains.
Our white sweat proof shirt works well under most dress shirt. If you wear a lot of white dress shirts, consider our sweat proof grey v-neck; it may seem counter-intuitive, but a grey undershirt is less visible under a white button-up. And don’t forget our black sweat proof v-neck to wear with dark-colored dress shirts or as a casual weekend shirt.
How is the cotton v-neck undershirt different from the micro modal undershirt?
To keep you looking dry we used micro modal in the underarm 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 in 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 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 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.
Definitely worth having. Wore them underneath playing golf. No more sweat stains even when it’s scorching hot.

Great buy! It keeps my shirts dry, no longer feeling uncomfortable and prolongs the life of my shirts.
Hi Nesanel, Thank you for your review. I am so happy to hear that your Ejis undershirts are keeping you comfortable and dry! Have a great day, Merrielle Ejis Customer Support
These shirts are phenomenal. I normally sweat through the underarms of my shirt in no time, but with these not even a trace of sweat all day long.
Hi Jason, Thank you for leaving a review! I am so happy to hear that your Ejis undershirts are keeping you dry all day long! Have a great day, Merrielle Ejis Customer Support
Good. But the size I ordered (2x) runs a little small for me. I will order 3x next time.
Hi Thomas, Thank you for sharing your feedback. I am so glad you are happy with your Ejis undershirt. I apologize the fit wasn't 100% perfect on the first try. Please feel free to email us at email@example.com if there is anything we can help with. Have a great day, Merrielle Ejis Customer Support
Truly a life changing product. My anxiety around sweating has gone down drastically, I can wear clothes I never would have worn before, and my confidence is boosted. I have been wearing the cotton v-neck shirts for a couple years and recommend buying a size smaller than usual because the extra layers around the armpit add bulk that isn’t as noticeable if you choose a snug fit. I want to buy more shirts with the added length to stay tucked. Wear a “black and white” anti-stain antiperspirant as with any white shirt, they will yellow over time and as of yet, I haven’t found a way to get rid of the stain. Perhaps because the interior layer is micro modal? I’m not sure. When will the L cotton V be back in stock???
Hi Will, Thank you for sharing your experience. I am so happy to hear that your Ejis undershirts have been life changing. For the stains, I recommend checking out our Care instructions on the FAQ page: https://www.ejisinc.com/pages/faq-new . We hope to have our L Cotton V-Neck Undershirt back in stock by the new year. I hope this information is helpful! Have a great day, Merrielle Ejis Customer Support
The shirts do the job by stopping sweaty underarm marks- but as they are regularly washed they have lost their ‘whiteness’ and have become yucky grey. So not major but annoying for an expensive garment
Hi Cathy, Thank you for sharing your feedback. I apologize that your undershirts have not kept their "whiteness". Please go to this link to see some tips on how to care for your Ejis products, which may help resolve this issue, please check out the Care Instructions section of our FAQ webpage: https://www.ejisinc.com/pages/faq-new .

Great product and works very well!
Hi Neil, Thank you for leaving a review. I am so happy to hear that your Ejis undershirt is working very well for you! Have a great day, Merrielle Ejis Customer Support
Well worth the price! I would never spend that amount for undershirts but after ruining too many shirts and being uncomfortable, I took a risk. It was well worth it. I recommend it.
Hi Nesanel, Thank you for leaving a review! I am so happy to hear that your Ejis undershirts were well worth the price. We appreciate the recommendation. Have a great day, Merrielle Ejis Customer Support
These shirts are pretty good. They last about a year before the seams around the underarm start weakening/splitting. (With regular washing in accordance with the Ejis-provided instructions, of course.) The marketing tag sewn to the bottom of the shirt also creates holes over time as the regular washing in the places where the tag's stitches are located. Overall the shirts work well.
Hi Michael, Thank you for sharing your feedback. I will send your comments on to our product development team. I hope you are loving your Ejis undershirt! Have a great day, Merrielle Ejis Customer Support
