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.

    100% recommend

    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.

    Total game changers

    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!

    Great Product, Very Effective!!

    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.

    Exactly what I was looking for!!

    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!!

    Works as advertised!

    So far, I love them! I have to wear dress slacks for work every day, and the sweat was becoming a real issue. I manage a team of people, and sweat stains are a real confidence killer! This has solved the problem for me, and I'm excited to expand my wardrobe options!

    Experience

    I’m happy these items are available, my high school kid came to me about sweating excessively. He is very embarrassed about it. So I’m glad this was here as an option. Hurts the pockets of the average Joe though.

    Hi David, Thank you for leaving a review. We understand that the price point is higher than a regular undershirt. This is due to the cost of manufacturing with premium micro modal & cotton, odor fighting silver infusion and sweat proof technology. I am so glad that your son is happy with his Ejis boxer briefs!

    Prevents sweat stains

    My son finds these boxers very effective at preventing sweat stains when he’s sitting on a chair. Very happy with these. They are expensive, but worth the peace of mind!

    Sweat Proof Boxer Brief with Fly size medium.

    I have been pleasantly surprised by this product. I was skeptical with my first purchase but upon wearing them now for a while I think they are much better than most other brands out there. They are comfortable, fit well, and don't have any awful odors like most brands. So far I will continue to reorder this product.
