What Our Customers Say...

Exactly What My Husband Needed
My husband had surgery recently and was struggling with leaks. These boxer briefs gave him back a sense of normalcy. They’re discreet, reusable, and most importantly, comfortable. I’ve already bought another bundle. Highly recommend for caregivers looking for a real solution.
-
Comfort That Doesn’t Compromise Style
After trying disposable pads, I never thought washable briefs could be this comfortable. These look just like my usual boxers, but they offer way better protection. I wear them to work, while traveling, and even at the gym
-
Feels Just Like My Regular Boxers
I honestly forgot I was wearing incontinence underwear. They’re soft, snug, and completely leak-proof. No shifting, no weird bulk, and nothing shows through my clothes. I’ve been able to go about my day with total confidence
-
Didn’t Expect to Love Them
These are a game-changer. I used to worry every time I left the house. Now I wear LEAKBOX briefs daily. They’re absorbent, don’t smell, and hold up after multiple washes. Way better than anything I’ve tried before
-
Better than expected
I was hesitant at first, but these work better than I imagined!

What material are LEAKBOX boxer briefs made from?
What material are LEAKBOX boxer briefs made from?
LEAKBOX 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?
LEAKBOX is the first boxer brief designed not only for light leaks but especially for moderate leaks. Our Neslemy9-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. LEAKBOX is a better choice for the planet because washable underwear reduces waste and your carbon footprint compared to disposable pads and guards.
What makes LEAKBOX better than other reusable incontinence brands
What makes LEAKBOX better than other reusable incontinence brands
Neslemy offers several key advantages over other reusable brands:
• Industry-first 9-layer protection system - For dribbles and 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
