Men’s Maximum Absorbency Washable Incontinence Boxer
Find your absorption level
Choose the right protection for your needs — or combine several for total peace of mind, day and night.
Our underwear is made to be changed after each leak, just like regular underwear. Most of our customers keep several pairs in rotation so they always have a fresh one ready.
We recommend owning at least 4 to 6 pairs so you can change during the day, wash, and rotate without ever running out.
For nighttime or heavier moments, we recommend the Heavy or Extra level for maximum dryness and full peace of mind — even on the busiest days.

Description
After overwhelming demand from our customers, we set out to design the most absorbent boxer brief in the world — built for men who need extra protection against heavy leaks, especially at night.
The result: the only underwear on the market capable of absorbing and locking in up to 20 fl oz of liquid, matching the capacity of a full adult diaper. No other boxer in the world delivers this level of protection.
Powered by our proprietary Orykas PureDry™ technology, this new generation features an enhanced multi-layer system built for extreme absorbency and maximum security. Designed for both day and night use, it provides ultra-reliable protection when you need it most — at home, while traveling, or while you sleep.
Slightly more substantial than our Ultra Absorbent version, it's engineered to fully replace bulky adult diapers with a discreet, comfortable solution that looks and feels like regular underwear. Stay dry, protected, and confident — without compromise.
Can I reuse them?
Our ultra-absorbent incontinence boxer shorts are built to last, with a reusable design that holds up for an average of 3 to 5 years.
How long can I wear them?
Our ultra-absorbent incontinence boxer shorts hold the equivalent of up to 16 regular pads. Depending on your flow, they offer up to 12 hours of day or night protection. For heavier leaks, we recommend changing them as soon as you start feeling damp.
What materials are the boxers made of?
Our boxers are made from 95% natural bamboo fiber and 5% spandex. This blend offers softness, breathability, and just the right amount of stretch for all-day comfort. Bamboo is naturally antibacterial and gentle on the skin.
Will this have a nappy effect?
Compared to our Light and Heavy versions, this Maximum Absorbency boxer is naturally a bit more substantial — that's the trade-off for its extreme absorbency capacity (up to 20 fl oz). However, it remains far more discreet, sleek, and comfortable than wearing an adult diaper, while delivering the same level of protection. You get diaper-level security with the look and feel of real underwear.
Which size to choose?
🧼 Not sure about the size? Don’t worry. Check out our size chart – our products follow standard American sizing. We recommend choosing your usual size. If you’re in between sizes, we suggest sizing up for a more comfortable fit.
Are these boxer briefs suitable for severe incontinence?
Yes — this Maximum Absorbency boxer is specifically designed for severe to very severe incontinence, including heavy nighttime leaks. With an absorption capacity of up to 20 fl oz, equivalent to a full adult diaper, it's the most absorbent boxer brief on the market and is engineered to handle leaks that other boxers simply can't contain. The integrated multi-layer technology, powered by our proprietary Orykas PureDry™ system, rapidly absorbs moisture and locks it in, while the natural antibacterial properties of bamboo fiber keep you fresh throughout the day. For continuous all-day or overnight protection, we recommend having several boxer briefs in rotation to ensure maximum security and comfort at every moment.
When is it preferable to purchase boxer briefs rather than diapers?
Washable incontinence boxer briefs represent an advantageous alternative to disposable diapers in several situations. For light to moderate incontinence, boxer briefs offer a dignified and comfortable solution that preserves your independence and self-esteem. If you're active and mobile, boxer briefs adapt perfectly to your lifestyle without the constraints of traditional diapers. From an economic standpoint, investing in 3 to 5 reusable boxer briefs (with a lifespan of 3 to 5 years) represents substantial savings compared to disposable diapers that generate recurring monthly costs. Finally, if you're environmentally conscious, our washable boxer briefs drastically reduce your waste – ORYKAS's 123,000 users avoid tons of disposable products daily. However, diapers remain recommended for very severe incontinence or situations with greatly reduced mobility requiring specific medical supervision.
Are boxer briefs more comfortable than diapers?
Yes, comfort is one of the main advantages of washable incontinence boxer briefs compared to disposable diapers. Our boxer briefs are made from 95% natural bamboo fiber certified OEKO-TEX, recognized for its exceptional softness and breathability. Unlike plastic diapers that can cause maceration, irritation, and uncomfortable sensations, bamboo naturally regulates temperature and lets your skin breathe. The absence of plastic also eliminates annoying rustling noises. Boxer briefs offer a natural textile fit that moves with you without friction, while diaper adhesives can sometimes create unpleasant rubbing. For sensitive skin, bamboo's hypoallergenic and antibacterial properties prevent skin irritations frequently associated with prolonged wear of disposable products. With up to 12 hours of protection, you enjoy the comfort of regular underwear with the effectiveness of high-performance protection.
