Description

They can hold up to 10 fl oz of liquid, making them ideal for light to moderate leaks. And for extra protection when you need it most, each pair comes with a removable absorbent pad that easily slips into place to boost absorption capacity even further.

Crafted from ultra-soft bamboo fiber, these boxers are not only breathable and naturally antibacterial, but also incredibly gentle on sensitive skin.

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 8 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?

Not at all. We've carefully selected all our materials to give you maximum comfort and a feeling of wearing ordinary boxer shorts.

Which size to choose?

🧼 Not sure about the size?
Don’t worry. Check out our size chart – we recommend going with your usual size. If you’re in between sizes, we suggest sizing up for a more comfortable fit.

📦 And if it doesn’t fit quite right, you can return it – as long as it hasn’t been worn.

(That way, we keep things perfectly clean for everyone!)

  • After years of dealing with pads that used to leak at the most inconvenient times, I’m really impressed with how well Jack's Ultra-absorbent Boxers hold up. I was also pleasantly surprised by how long I can wear them without feeling damp.

    Carl K.

  • Truly ultra-absorbent compared to any other urinary leak boxers I’ve tried.

    John V.

  • These boxers have given me my confidence back. I can go out without worrying about leaks… and, between us, my wife definitely prefers seeing me in these boxers rather than in a pad.

    10 fl oz Absorption Test

    Other Brands vs Jack

    No one comes close to matching our absorption capacity. We’ve spent years developing an ultra high-tech fabric that combines maximum absorbency with lightning-fast drying – giving unbeatable protection and comfort, all day long.

    Not the same elegance

    Same capacity absorption

    Disposable pads may do the job, but they’re bulky, uncomfortable, and, let’s be honest — they don’t exactly make you feel confident. On top of that, they’re full of synthetic materials and chemicals that can irritate your skin.

    Jack's Boxers give you the same leak protection without the downsides. No chemicals. No plastic feel. Just ultra-soft fabric that looks and feels like proper underwear. Stay dry, stay confident — no one needs to know.

    Customer Reviews

    No More Worries!

    I used to carry spare underwear everywhere "just in case." Since switching to Jack's Boxers, that’s a thing of the past. No hassle, no embarrassment. The fabric is durable yet soft, and the fit beats most regular boxers I’ve tried.

    Stephen (64)

    Worth Every Penny

    My wife encouraged me to give them a shot, and I’m impressed. I love working out, but post-urination dribble was a minor annoyance. Not a huge issue, but uncomfortable. Now I don’t have to keep checking for visible spots.

    Gary (59)

    Incredibly Comfortable.

    As a manager, I’m stuck in long meetings with few breaks. A bit of urine leakage used to stress me out. Jack's Boxers have set me free. No stains, no odour, and zero worries. The fit is spot-on too.

    Colin (57)

    Works Like a Charm!

    Finally, a boxer that delivers on its promises. No more wet spots after a walk or drive. They’re comfy and don’t have that plasticky feel some brands do. Wish I’d made the change sooner.

    John (55)

    Fantastic Solution!

    After my prostate surgery, I dealt with occasional small leaks. Nothing major, but enough to make me self-conscious. Jack's Boxers have completely fixed that issue.

    Eddy (68)

    No More Stress!

    As a busy dad, minor leaks after peeing were a hassle at work. Jack's Boxers fixed that. Comfy, absorbent, and they look like regular underwear. No more worries!

    Mark (42)

    Total Game-Changer!

    I run a lot and used to stress about post-workout dribble. Jack's Boxers fit great, feel soft, and keep spots hidden. Wish I found them sooner!

    Tom (39)

    FAQ

    Do I have to pay for shipping?

    Email: support@jacksboxers.com

    How does the leak-proof technology in the boxer work?

    Jack's Boxers use a unique 4-layer system in the crotch area, engineered to keep men dry, comfortable, and confident all day:

    ✔️ Layer 1: Quick-Dry Comfort Layer
    This top layer instantly pulls moisture away from the skin, reducing irritation. Infused with antibacterial silver, it fights up to 99% of bacteria — keeping you fresh and clean around the clock.

    ✔️ Layer 2: High-Absorbency Core
    The absorbent centre locks in liquid and controls odour. It holds up to three times more than ordinary fabrics — giving protection whether it’s light drips or more frequent leakage.

    ✔️ Layer 3: Protective Leak Barrier
    A thin, breathable shield that blocks leaks without adding bulk. Designed to last through 1,500 washes, it provides long-term, dependable protection.

    ✔️ Layer 4: Soft Outer Shell
    Made from a stretchy cotton blend, the outer layer feels like regular boxers. No stiff textures, no “medical look” — just stylish, discreet underwear you’ll actually want to wear.

    How do I wash the boxers?

    How to wash my boxers properly:

    1. Rinse the boxers thoroughly with cold water first to remove any excess moisture.

    2. Use a mild detergent and select a cold wash cycle or a maximum of 30°C.
