A truly great boxer brief offers comfort, design, and functionality – our Ejis sweat proof boxer briefs with fly 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. We added a fly to this design for guys who prefer that style.
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 comfort pouch.
We don't just make clothing, we make Wearable Confidence.
EXTRA LARGE COMFORT POUCH - Keep your junk separated and cool, but also have easy access.
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.

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.

Hi Mike, Thank you for leaving a review. I am so happy to hear that your Ejis boxer briefs are perfect! Have a great day, Merrielle Ejis Customer Support
I bought this for my husband as a birthday gift, so far he absolutely loves them. Although I have to admit I kinda bought them for him so he would do me a favor in return...because of the sweat problem and living near the Coachella Valley, during the hot season he tends to shave. And it might be great for his relief of uncomfort, but for me...not so much! :0( So why not us both be happy and content? Thank you for designing such a wonderful product, can't wait to see any future new styles and designs. By the way, we're strong supporters of small businesses, they are the backbone of this great nation ;0)
