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.

    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! Have a great day, Merrielle Ejis Customer Support

    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.

    Works as advertised

    I have worn the sweat proof boxer briefs on and off for a couple of weeks and they do prevent sweat from going through to the pants. The only drawbacks I’ve encountered is the back of the underwear rides down a little low, but not enough to experience “Plumbers Crack”…my assumption is because the added sweat blocking material weighs them down a little. The other is your butt stays a little moist. I haven’t experienced any chafing, but I haven’t been too active in these yet (long hikes, sports). If you’re like me and sleep in your underwear, it would be a good idea to swap out with a regular pair…your butt and nether-regions will stay moist. In general, I would recommend these to anyone who profusely sweats; but take the opportunity to let your undercarriage breath a little when you get back home from your sweaty adventures.

    Bought as gift

    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)
