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.

    Keep coming back

    I’ve worn these undershirts for a few years now. Absolutely perfect in every way possible. Ace’s in the style pyramid. Functions in exactly the way it says it should. Fabric is soft sturdy and breathable. Fit is close to body to where you almost don’t feel it but know it’s doing it job. I’ll continue keep coming back.

    Scoop neck T's

    The cotton scoop neck T's are great, so I took the chance to buy a couple of the Micro Modal deep v's -Fantastic! THE MATERIAL FEELS SO GOOD. THE DEEP V's Let your dress shirts not show from underneath your shirt and the additional advantage is you don't sweat! UNBELIEVABLE AND UNMATCHED

    Life Changer

    Great service and quick shipping from Ejis. On top of that the quality of these shirts is amazing. I have been looking for something like this for a long time. I can finally go back to wearing white dress shirts this is a life changer for me.

    Does exactly what I need it to do!

    Love this undershirt! I'm on our worship team at church and raising my arms constantly, now I can do it freely without any fear or embarrassment. Also, side note, I tried the Thompson Tee and this one is definitely superior!

    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.

    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.

    SUPERB PRODUCT, WONDERFUL CUSTOMER SERVICE

    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!

    Amazing

    Love these shirts, They give me the confidence required with dealing with the public as I do on a daily basis due to my job. No longer do I feel they are looking at my armpits thinking “the hells wrong with this guy? It’s not even hot” I’ll be a life long customer and returning often to purchase more.

    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.
