How many pairs of boxer briefs do I need?
It's completely up to you and how you plan to use them. Many customers wear them every day as their regular underwear, so they buy several pairs to have some in the laundry and clean ones ready in the drawer. Most people start with 4 pieces.
How do I wash these boxer briefs?
How do I wash these boxer briefs?
Wash your Menvault boxer briefs just like regular underwear with standard laundry detergent in warm water. The bamboo fibers have natural antibacterial properties that help maintain freshness during washing.
For best results:
- Use a mesh washing bag to protect the fabric during the wash cycle
- Air dry or use low heat in the dryer
- Avoid fabric softeners as they can reduce absorption

What material are Menvault boxer briefs made from?
What material are Menvault boxer briefs made from?
Menvault boxer briefs use OEKO-TEX® certified materials in a 9-layer system. The main body is 95% bamboo and 5% spandex for comfort. The absorption layers combine bamboo and polyester for moisture management, with a waterproof nano-polyester backing to prevent leaks.
The bamboo provides natural antibacterial properties and softness, while the polyester layers handle absorption and wicking. All materials are tested for safety and skin contact.
How often do you change these boxer briefs?
How often do you change these boxer briefs?
These underwear are designed for light and moderate leaks. How long you can wear them depends on how much you leak, since everyone is different and leaks can be unpredictable. However, most customers with moderate leaks change them every 12 hours.
How do they work?
How do they work?
Menvault is the first boxer brief designed not only for light leaks but especially for moderate leaks. Our MultiVault™ 9-Layer System is built right in. When leaks happen, the top layer quickly pulls moisture away from your skin. The absorbent core locks in liquid and traps odors. The waterproof outer layer keeps everything contained, so nothing leaks through. You stay dry, comfortable, and protected all day, just like wearing regular underwear.
Is washable leak-proof underwear a planet friendly choice?
Is washable leak-proof underwear a planet friendly choice?
Yes, absolutely. That's why they've become so popular. Menvault is a better choice for the planet because washable underwear reduces waste and your carbon footprint compared to disposable pads and guards.
Are they hygienic?
Are they hygienic?
Yes, they're completely hygienic. Our antibacterial bamboo fabric prevents bacteria growth and keeps you fresh all day. After wearing them, just wash them like regular underwear and they're clean and ready to wear again. The MultiVault™ system is designed to be washed repeatedly without losing its protective qualities.
What makes Menvault better than other reusable incontinence brands
What makes Menvault better than other reusable incontinence brands
Menvault offers several key advantages over other reusable brands:
• Industry-first 9-layer protection system - For Light and Moderate leaks (most competitors use only 3-4 layers and only focus on dribbles/light leaks)
• Male-specific engineering designed for actual male leak patterns, not adapted from women's products
• 300ml capacity with invisible compression technology that maintains regular boxer brief thickness
• OEKO-TEX® certified bamboo fibers for natural antibacterial properties and skin safety
• Dries 3x faster than competitors for better hygiene and comfort
Most reusable brands focus on basic absorption only. Menvault integrates absorption, wicking, odor control, and antibacterial protection in one system while maintaining the exact look and feel of premium underwear.
Customer Reviews
Been dealing with bladder issues for two years and dreaded long meetings. I am a heavy wetter when it happens. These boxers saved my career, no more excuses to leave presentations early. Game changer for any guy in the same boat.
Hi Ben,
Thank you for sharing your experience! We're so glad our boxer briefs have helped you feel confident during meetings and presentations. Stories like yours are exactly why we do what we do.

MenVault
complete leak protection during long meetings. Zero odor, stays in place perfectly
My prostate surgery left me with some leaking issues and I was constantly worried about accidents during my sales calls. These give me the confidence to focus on closing deals instead of finding the nearest bathroom.
Figured they'd be bulky like diapers but they're not. Fit under my jeans fine and don't make noise when I walk. Only wish they came in more colors.
Hi Ryan,
Thanks for the great feedback! We're thrilled you love the comfortable, discreet fit. We really appreciate the suggestion about more colors - we're always looking at ways to expand our options and will definitely pass this along to our product team.
Best regards,

MenVault
good quality. They dry very fast.
Handles my incontinence without chafing or rolling down. Discreet delivery was appreciated too.
First thing I noticed is that these look like any other pair of underwear (not men’s diapers).
They fit comfortably and stay in place as you would expect and keep moisture away from your body. Cost is comparable with other protective underwear and worth it. I feel confident while it work or going out to dinner with these on.
