"The added layer in the pouch of these underwear is perfect. Catches all the extra dribbles and keeps it from showing through on pants. Nice supportive fit that doesn't ride up."

Product Description

Stop the chafe before it starts. The MNTD Men’s Buffer Boxer Trunk is your secret weapon against daily discomfort. Featuring a shorter 3" inseam, this trunk provides a sleek "buffer" of friction-reducing fabric between you and your clothes, effectively preventing irritation and skin-on-skin rubbing. Made from a lightweight, breathable blend that wicks moisture away, these anti-chafe boxer trunks stay in place without the bulk of a longer leg. It’s the ultimate solution for men who want maximum protection in a minimalist silhouette.

Moisture Controlled

Built-in Pristine Pouch Plus™ triple-layer buffer absorbs and wicks away liquid to help prevent awkward moments.

Fresher for Longer

Super breathable, anti-odor Mint Condition Technology™ for optimal freshness.

Love the Feel

Soft organic cotton body fabric that moves comfortably with you, while the waistband stays in place without digging in.

No Adjustments Necessary

Designed to prevent sagging, bunching, or ride-up with durable construction that holds its shape over time.

    Absorptive trunk

    As this is the first time I have tried this kind of underwear , I have nothing else to compare to. These are what I have been looking for later in the day. I have no problem with leaks overnight or through the mornings . So I can recommend them

    Great fit and comfortable feel

    There are great boxers! Had surgery months back and the added protection and insurance is a welcome addition to the comfort of the boxers. I would highly recommend.

    Surprisingly Excellent "Absorbent

    Who expects men's underwear that handles "leakage" to be attractive & comfortable? Pretty much no one until MNTD. I don't hand a major problem, but at times I do have enough of any issue to worry. No more. My NNTD boxers do the trick and look good

    Best briefs ever

    I thought these would be another overpriced pair of underwear, but after wearing them for a few days, I noticed they were extremely comfortable and protected me without the need for pads. I highly recommend them for those men who need protection from embarrassing moments. Well worth their price.

    A little tight…

    Maybe run a little small (hence the minus one star…) but otherwise I am liking them in terms of quality and functionality.

    Really like these

    These are very comfortable and soft. And the added benefit of knowing you'll never be embarassed by dribbling in your pants is a game changer

    Recommend

    Comfortable, really like the shorter leg length, the leakproof pad works and provides reassurance when wearing light coloured dress pants. The legs ride up a bit but with the shorter length it wasn’t too bothersome for me.
