“Genuinely indistinguishable from regular boxer briefs.” — Michael K.
People often mistake KENKO for just another clothing brand because of how comfortable and stylish our underwear is. But KENKO was built for a bigger purpose: to help men dealing with embarrassing below-the-belt issues feel confident and comfortable in their own skin again. Please check out our supplement that helps support the benefits of the KENKO underwear.
YES! KENKO underwear is fully machine washable and won't shrink or lose its shape. They're built to last through over 200 washes—which saves you from throwing away hundreds of disposable diapers.
WARNING: You'll have the best sleep you've ever had wearing KENKO underwear to bed. Side effects may include: extreme comfort, waking up dry, and no awkward morning explanations.
Don't stress, we're here to support you during and after your purchase. If your first KENKO pair doesn't fit quite right, we make exchanges easy so you can find your perfect fit. Check out our Returns & Exchanges policy for the details, or just reach out to our support team—we're happy to help you pick the right size or even exchange a pair for our supplements.
