A truly great boxer brief offers comfort, design, and functionality – our Ejis sweat proof boxer briefs with comfort pouch have all three in spades. Sweaty underwear doesn’t have to ruin your day.
We founded Ejis based on the belief we could make you feel more confident by solving two of your most embarrassing problems: sweat marks and odor. We've woven intelligent design, world class functionality, and unrivaled comfort into our sweat proof boxer briefs to give you what we call "Wearable Confidence."
Our sweat proof, anti-odor underwear is made with super soft, breathable micro modal material, fused with real silver to fight odor causing bacteria. Combine that with an ultra-thin waterproof layer in the places you need it most, and you get a powerful pair of moisture wicking boxer briefs that keep you dry and comfortable.
With Ejis boxer briefs, your butt, back of the legs and crotch are all protected with an ultra-thin waterproof layer that stops sweat from transferring to your pants, so you stay looking your best and feeling confident. Forget embarrassing sweat marks on your pants or shorts – this anti-sweat underwear for men is an absolute game changer. Don't be surprised if you try a pair and want to replace your entire underwear drawer.
All Ejis sweat proof underwear are engineered from the ground up specifically for the exceptional man who wants an unfailing, discreet solution to sweat marks and bad odor. Join the thousands of men who are now able to wear what they want because of their Ejis underwear. Need a different style? Check out our sweat proof boxer briefs with fly.
We don't just make clothing, we make Wearable Confidence.
EXTRA LARGE COMFORT POUCH - Keep your junk separated and cool.
EXTRA WIDE WAISTBAND - No waistband digging in to undo all the comfort the rest of these boxer briefs provide.
PERFECT LENGTH - Plenty of protection and comfort.
BACTERIA-FIGHTING SILVER TO COMBAT ODOR - Silver is permanently bound to the fibers of each pair of sweat proof underwear, which keeps you fresher longer. It also helps to regulate your body temperature by pulling heat away from the body when you're hot.
SUPER PREMIUM MICRO MODAL FABRIC – Twice as soft and 50% more water-absorbent than cotton. With 5% Spandex to add stretch, it will possibly be the most comfortable men's underwear you've ever worn.
WHAT THIS UNDERWEAR WON'T DO is make your sweat disappear, unfortunately, it's not that good. It may feel damp but it won't show on your pants.

First Product Guarantee
Buy one undershirt and one pair of boxers and try them out risk-free! If you don’t love them, we’ll send you a different size or issue a refund. No return required. Visit the FAQs for details.
Satisfaction Guarantee 45-day Return Policy
If it’s not covered by our First Product Guarantee, we’ll still issue a refund or process an exchange for orders returned to us within 45 days of purchase.

Visit the FAQs for details.
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.
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.
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.
The underwear alone performs well and as advertised does exactly what it’s supposed to do. No embarrassing signs of “butt sweat” so I can work and walk through the office with confidence. But the unexpected surprise was the response from EJIS when there was a minor issue after wearing and washing them twice. I emailed a complaint thinking “here we go.” Understandably I need to provide some information and pictures, I failed to provide everything. Yet still, EJIS provided exemplary and timely response leading to my complete satisfaction. I would shop and buy from them again without hesitation. Well done EJIS !!
Top notch. Very pleased.
I wasn't sure if these underwear would work for a sweaty butt but they seem to be working great. Thank you
These are great - wish they made a slightly lighter version though! Have both shirts and briefs and both work well for preventing stains - good piece of mind for work, dates, etc.
I like the quality of material and it serves its purpose well.
School teachers like me differ from marathon runners in one important respect: in addition to running around all day, we have to maintain at least a moderate degree of respectability in the eyes of individuals constantly on the lookout for our slightest foible, our minutest mishap... Before Ejis, I suffered and apologized. Now, I command the room---all day, every day! To all my hyperhidrotic fellows, yearning to be free of your "shame," know this: Ejis is the KEY to your salvation! If you're in doubt about the efficacy of these extraordinary products, let my words tip the scales in everyone's favor: GO FOR IT!
I got them for my son. He states he still feels a bit damp but there is no breakthrough through his clothing. This is a big deal for him, he is really happy with the product. I got him some t-shirts as well but his has not tried them yet.
Hi Kathleen, Thank you for leaving a review! I am so happy to hear that your son is happy with his Ejis boxer briefs. I hope he loves his undershirts just as much. Have a great day, Merrielle Ejis Customer Support
This is the first underwear that I can wear with certain pants and be comfortable knowing I won’t sweat through. Although it is pricey, it is worth it and I will be buying more.
