Menvault suits most guys dealing with:
Post-Surgery (e.g., Prostate)
Exactly who we built this for. The 9 layers handle what you're facing right now, while you recover.
Stress Incontinence
Leaks when you cough, sneeze or lift something? Taken up fast, before it shows.
Post-Void Dribbles
That last bit after you've already left the bathroom. Irritating, but covered. No wet spot. No pad.
Urgency / Sudden Leaks
You can't always make it in time. These give you the seconds you need, without the embarrassment.
Night-Time Protection
Wake up dry. The Vault holds up to 10.14 fl. oz for 12 hours. Sleep without giving it a thought.
Not sure if Menvault is right for you?
If you leak more than 10.14 fl. oz (300ml, about one full can of soda) or you depend on diapers every day, Menvault probably isn't the right fit. We'd rather be straight with you than take your money.
Which size should I pick?
Which size should I pick?
Look at the size chart and take your usual underwear size. Between sizes? Drop one down.
Wrong fit? We'll exchange them, even once you've tried them on.
Will they look bulky or feel like a diaper?
Will they look bulky or feel like a diaper?
No. All 9 layers are pressed into a thin build. No bulk. No crinkle. No diaper outline. Looks and feels like ordinary underwear. In the locker room, under fitted pants, anywhere. Nobody can tell.
Are they easy to wash?
Are they easy to wash?
Yes. Machine wash at 30°C (inside out), mild detergent, air dry, no fabric softener, no ironing. That's all. Cared for that way, each pair lasts up to 3 years.

CUSTOMER VOICES
DON'T JUST TAKE OUR WORD FOR IT.
"I started with Prevail guards because the pharmacy had them. They did the job, but I was swapping 2 or 3 times a day and the rustle drove me up the wall at the office. Moved to Menvault a few months back. Wore them to a work dinner last week. Sat down, stood up, walked to the car. Nothing showed, nothing moved. I barely thought about it."
"After surgery I mostly deal with stress leaks. I had settled on Tena Guard Max, bought online as the best value for coverage. Then I tried the Menvault boxers and I'm very pleased. I coach tennis, and through 2 hours of hitting they keep me dry and make me feel secure. Really recommend them."
"14 years clear since my RALP, and I'm 77 now. Last month I moved from Northshore pads to Menvault boxers. They cost more up front, but after years of pads I won't go back. The boxers give better comfort and leak protection through all kinds of physical activity. I'm back in thin khakis without worrying about leaks."

Frequently asked questions
STILL WONDERING? WE HAVE THE ANSWERS
How does the built-in MultiVault protection work?
How does the built-in MultiVault protection work?
Menvault relies on a 9-layer system, with each layer handling one job and handling it well.
The instant a leak occurs, the first layers soak it up and dry quickly, so nothing sits against your skin. No dampness. No irritation.
From there, the liquid is drawn deeper into the fabric and held inside for up to 12 hours. Bamboo fibers naturally tame odor. No added chemicals, no smell, no need to change straight away.
The final layers form a full barrier. Very little passes through and almost nothing reaches your clothes.
You stay dry, fresh and fully in control. Throughout the whole day, every day.
How many pairs should I start with?
How many pairs should I start with?
It depends on how you wear them. Most men begin with 4 pairs, so a clean one is always ready while the others are in the wash.
Will I stay fresh wearing them all day?
Will I stay fresh wearing them all day?
Yes. The 9 layers keep you dry. Bamboo helps stop bacteria from building up. Little to no odor. No dampness. Most men switch them after 12 hours or before bed, just like regular underwear.
Is Menvault kinder to the planet?
Is Menvault kinder to the planet?
Yes. One pair takes the place of hundreds of disposable pads. Less waste, less rubbish, kinder to the planet.

What sets Menvault apart from other leak-resistant boxers?
What sets Menvault apart from other leak-resistant boxers?
Most leak-resistant boxers on the market have 4 to 7 layers, basic cotton fabric and cover only the front. They handle light drips at best and aren't built to last.
Menvault has 9 layers placed right where men leak: front, back and sides. Bamboo fabric that soaks up fast, dries quickly and holds up through hundreds of washes. Made for drips, light and moderate leaks. Up to 300ml. No bulk. Hardly anyone can tell.
We didn't rely on lab tests alone. Men who know what's at stake wore them first, and that's the test that counts most to us.
Do I always need the washable guard?
Do I always need the washable guard?
No. The boxer brief works well on its own. The 9 layers handle light to moderate leaks without the guard. Add it when you want extra security, and leave it out when you don't.
Does the boxer brief have a fly opening?
Does the boxer brief have a fly opening?
No, our Light & Moderate Leaks version has no fly opening. That design choice was made to help reduce leaks.
