Will they hold my leaks?
Will they hold my leaks?
Built for dribbles, light leaks, and moderate leaks. Holds up to 10.14 fl oz (300ml). Absorbs fast and locks it in.
Clenvox works for most guys dealing with:
Post-Surgery (e.g., Prostate)
Exactly who we built this for. The 9 layers catch what you’re dealing with right now, while you recover.
Stress Incontinence
Leaks when you cough, sneeze, or lift something? Absorbed fast before it shows.
Post-Void Dribbles
That last bit after you’ve already been to the bathroom. Annoying but handled. No wet spot. No pad needed.
Urgency / Sudden Leaks
Can’t always make it in time. These buy you the seconds you need without the embarrassment.
Night-Time Protection
Wake up dry. Holds up to 10.14 fl. oz for 12 hours. Sleep without thinking about it.
Not sure if Clenvox is right for you?
If you leak more than 10.14 fl. oz (300ml), about one full can of soda, or you rely on diapers daily, Clenvox is probably not the right fit. We’d rather be honest with you than have you waste your money.
Which size to choose?

Not the right fit? We’ll exchange it. Even if you’ve tried them on.
Will they look bulky or feel like diaper?
Will they look bulky or feel like diaper?
No. All 9 layers are compressed into a thin construction. No bulk. No crinkle. No diaper outline. Looks and feels just like regular underwear. In the locker room, under fitted pants, anywhere. Nobody can tell.
Are they easy to wash?
Are they easy to wash?
Yes. Throw them in the machine wash at 30°C (inside out), use mild detergent, air dry, no fabric softener, no ironing. That’s it. With proper care each pair lasts up to 3 years.

Don’t take our word for it.
“Nothing showed. Nothing shifted.”
Tried the Prevail guards first because I could grab them at the pharmacy. Worked OK but I was changing 2 to 3 times a day and the crinkle drove me crazy at work. Switched to Clenvox a couple months. Wore them to a work dinner last week. Sat, stood, walked to the car. Nothing showed. Nothing shifted. Didn’t think about it once.
“They really keep me dry.”
After surgery I am dealing mostly with stress leaks. I settled on Tena Guard Max purchased online as the best coverage/price point item. But then I tried the Clenvox boxers and I’m very satisfied. I coach tennis and through 2 hours of hitting they really keep me dry and make me feel secure. Really recommend.
“I will never go back to pads.”
14yrs clean since RALP. I’m now 77. Last month I’ve switched from Northshore pads to Clenvox boxers. I agree they may be a bit pricey upfront but after years of pads I will never go back to pad. The boxer offer superior comfort and allow for leak protection while engaging in a wide range of physical activity. I’m back to wearing thin khakis without fear of leakage.

Frequently asked questions
Questions? We got answers
How does the built-in protection work?
Clenvox uses a 9-layer system, each layer doing one job and doing it perfectly.
The moment a leak happens, the first layers absorb it instantly and dry fast, so nothing sits against your skin. No dampness. No irritation.
From there, the liquid is pulled deeper into the fabric and locked inside for up to 12 hours. Bamboo fibers neutralise odour naturally. No chemicals, no smell, no need to change.
The final layers act as a complete barrier. Nothing gets through. Nothing ever reaches your clothes.
You stay dry, fresh, and completely in control. All day, every day.
How many pairs do I need to get started?
That depends on how you use them. Most guys start with 4 pairs so there’s always a clean one ready while the others are in the wash.
Will I stay clean and fresh wearing them all day?
Yes. The 9 layers keep you dry. Bamboo stops bacteria before it builds up. No odor. No dampness. Most guys change them after 12 hours or before bed. Just like regular underwear.
Is Clenvox better for the planet?
Yes. One pair replaces hundreds of disposable pads. Less waste, less trash, better for the planet.
What is Clenvox made of?
Soft, breathable bamboo fabric. 95% bamboo, 5% spandex.
Layers 1, 2, 3: Polyester microfiber.
Layers 4, 5, 6: Superabsorbent microfiber and bamboo viscose.
Layers 7, 8, 9: TPU film. Thermoplastic polyurethane.
What makes Clenvox different from other leak-proof boxers?
Most leak-proof boxers out there have 4 to 7 layers, cheap cotton fabric, and only cover the front. Built for light dribbles at best. Not made to last.
Clenvox has 9 layers placed exactly where men leak. Front, back, and sides. Bamboo fabric that absorbs quick, dries fast, and outlasts hundreds of washes. Built for dribbles, light leaks, and moderate leaks. Up to 300ml. No bulk. Nobody can tell.
And we didn’t test this in a lab. Real men who know what’s at stake wore them first. Because that’s the only test that matters.
Do I always need to use the washable guard?
No. The boxer brief works perfectly on its own. The 9 layers handle light to moderate leaks without the guard. Use it when you need extra security. Skip it when you don’t.
Is there a fly opening in the boxer brief?
No, our Light & Moderate Leaks variant does not have a fly opening. This design choice was made to help prevent leaks.
