Size Guide

  • IMPORTANT SIZING INFORMATION: Order one size down to ensure a slim fit.

    Introducing the deep v-neck undershirt men feel confident in by design.

    Go ahead…unbutton those top two buttons. The Ejis Deep V undershirt is our deepest v-neck ever – deeper and wider than our regular v-neck tee, so you never have to worry about your undershirt showing. Look good and feel confident at the club, at the office, or on a date. If you’re like most men, these deep v-neck undershirts will soon be a staple of your wardrobe.

    Our Deep V doesn’t just look good – it’s sweat proof by design, too. The micro modal fabric is super lightweight to keep you cool, and the sweat proof armpit area keeps your dress shirts and polo shirts free of sweat stains. Don’t believe us? Read our customers’ reviews. We’re confident you’ll never buy another undershirt once you try one of our micro modal sweat proof shirts.

    You know it looks good. You know it’s sweat proof. Did you know it’s comfortable, too? We’re pretty sure our Deep V undershirt the most comfortable undershirt ever – but try it and find out for yourself. That super-soft micro modal sweat proof fabric has just the right amount of stretch. A deep v-neck undershirt that looks good, feels good, and keeps you dry? Finally, a undershirt men can get excited about!

  • 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 sweat proof shirts, 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. 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 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 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.

    Ejis Micro Modal Deep-V Sweat Proof Undershirt Review

    Wow. It really works. Normally I’m soaked. Not any more.

    Unbelievable. Had it on all day. Texas humidity. Not a single drop of sweat on my shirt. I am about to buy my son in law to be two shirts. Awesome.

    Hi William, Thank you for sharing your experience. I am so happy to hear that your Ejis undershirt kept your outer shirt dry all day in the Texas humidity! Have a great day, Merrielle Ejis Customer Support


    What I was looking for

    I loved all of Ejis shirts, but this deep V works better under my dress shirts!!!!

    Hi Jay, Thank you for leaving a review. I am so happy to hear that you love your Ejis undershirt! Have a great day, Merrielle Ejis Customer Support


    Really good product

    Fine; it does the trick, allowing me to wear shirts open two buttons with some sweat and chill protection. I’d also like you folks to make a very lightweight version of the deep-V shirt. It might not offer the same degree of sweat protection, but it would be great for high summer or semi-tropical climes (like HI in the winter when evening temps are 70-72). I had a couple in silk from a maker long gone, but they are worn out.

    Sometimes you want to hide a v or crew neck

    It's a really deep V, which is what I was looking for. Sometimes I don't want the appearance of an undershirt. All of the products from Eji's work tremendously.

    Surprisingly better than expected

    These work as advertised and are very comfortable to wear. No more wearing sport coats all day to cover the underarm embarrassment!

    Hi Damian, Thank you for leaving a review! I am so happy to hear that your Ejis undershirt is doing exactly what you expected. Have a great day, Merrielle Ejis Customer Support


    Great shirt!

    The shirts work great. What I most like is that I can wear a smallish tee shirt over my deep V neck Ejis, and you can't even see the undershirt. It is discrete and effective. Great product.

    I rarely write reviews. I think I've written two reviews of products in my life, and this marks my third. First, the shirt itself. This thing is magic. I sweat more than anyone I have ever met, and I had tried everything from dermatologists to pads, and medicine to prescription deodorant. I spent hundreds of dollars on other shirts (including the famous Numi, which does not work at all) before finding Ejis. Nothing, and I mean nothing, worked. Then I discovered these shirts. And THEY WORK. I have been wearing these shirts for over a year, and I have only experienced one bleed-through, and it was due to my poor planning, not product failure. The micro-modal material is incredibly comfortable, I really do feel cooler, and it's essentially invisible under most shirts. The only issue is that I need a size XS, and the Ejis business is clearly going gangbusters because they are consistently out of the XS. And that's where the second part of this review comes in. I would like to give a heartfelt shoutout to Julie from Ejis Customer Support. I emailed Ejis to ask a question about a different shirt I had purchased, and Julie was the one who replied. She was prompt, thorough, kind, and professional. I was so impressed with the depth of her response that I decided to ask if Ejis allows pre-orders for the extra small shirts, and it turns out they do! Julie set up a special pre-order for me, and she helped me through the process from start to finish. When there was a small error, she corrected it immediately. When it took me over a week to respond to one of her questions, she still remembered me and treated me with kindness. I have NEVER had a customer service experience like this one, and I will be a lifetime Ejis fan as a result of their superb product, and their even better customer service, as evidenced by the incredible Julie. Thank you Ejis, and thank you Julie!
