I have enjoyed wearing these boxers. It is great knowing that I am controlling my sweat instead of it controlling me. I don't have to worry about sweat stains or marks anymore.– Cody M.

Drove 6 hours in khaki pants no marks. Used to not even be an option. I can say that these genuinely have helped me. If you suffer from sweat stains, I implore you to try these out.

Was looking for an option to prevent embarassing blood stains on my shorts due to hemorrhoids. These work great - what a relief not to have to worry about that anymore!
Hi Chris, Thank you for sharing your experience. We appreciate your feedback. Best, Wilbur, Ejis Customer Support
Have purchased 2 pairs of the boxers and 1 undershirt. They are great quality and extremely comfortable. You will not sweat through this clothing. I will buy more and highly recommended.

If you have a puddle after sitting or sweat mark on pants, these are the answer. We tried powders, antiperspirants, moisture wicking underwear and nothing worked. Sitting in class with sweat dripping/ nothing gets through these underwater. Need a few pair- they take a while to dry after washing.

Overall, this is one of the best products I’ve tried. I wish the shirt had full coverage, my torso and shoulders still come out soaked with sweat after a workout.

Sweat blocking and comfy! Pretty much true to size, I’m an XL but ended up going with L as a gut feeling and they are a good fit, no looseness or sag, or sweat etc. shown and I wear these for up to 14hr days when at work. Keep in mind if you put a pair on and they don’t fit they can’t be returned so be mindful when ordering!

Hi Michele, Thank you for leaving a review. We are so happy to hear you love your Ejis Sweat Proof Men's Boxer Briefs with Fly. Best, Wilbur, Ejis Customer Support
I’ve been wearing these for about a week now and I wish I would’ve purchased them sooner. Point of reference: prior to purchase, I had the dreaded sweat line in every single pair of pants I owned (usually after 20 minutes, in any weather). So to be able to wear pants fright-free, big big big win! The cons: it’s definitely a noticeably different feeling than boxers. After you become damp, the feeling doesn’t go away and the back starts to sag. At home, I immediately change out of them. BUT your pants will stay dry!! The other con is the obvious cost - but trust me… it’s worth it.

Hi Ron, Thank you for leaving a review. We are so happy to hear you love your sweat proof boxer briefs with fly. Best, Wilbur, Ejis Customer Support
These things work - completely, every time, without fail. I've now been wearing sweat proof briefs for over 3 years with every different type of pants and shorts I own, all sorts of light and dark colours and materials, casually and at work. Not one problematic embarrassing appearance of sweat - not once! Not even a little bit. I trust them to work every time. I've stopped worrying and freaking out and they've given me confidence to wear what I want, when I want. And they don't wear out easily due to the amount of perspiration like normal underwear/fabrics so they are worth the spend. Brilliant products. Thanks so much! Total game changers!
Hi Bradley, Thank you for leaving a review. We are so happy to hear you love your Ejis Sweat Proof Boxer Briefs with Fly. Best, Wilbur, Ejis Customer Support
Highly recommend these boxers. This product certainly does the job as advertised. They are very comfortable and, although time will be the true test, the quality seems excellent. Unfortunately these are insanely expensive for an Australian buyer by the time you add freight and currency conversion, but they work so I guess it's worth it.
Hi Graham, Thank you for sharing your experience. We appreciate your feedback. Best, Wilbur, Ejis Customer Support
It works as advertised. I am an overweight guy whose work requires wearing suits and/or khaki pants everyday. I used to have to stand at my desk periodically throughout the day just to let the sweat lien dry. These boxer briefs have eliminated my problem. I plan on ordering one for every day of the week! Highly recommend!!
