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.

    Life saver

    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.

    Dependable product has been for years

    I’ve been wearing this product for years and it’s always been dependable, durable and comfortable, especially the ones with the pouch fly. Expensive but worth it! “SPOON”

    Great for Hemorrhoids

    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!

    Excellent

    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.

    These work!!

    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.

    Looking forward to athletic apparel

    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.

    It works!

    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!

    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!!
