For heavier leaks, we recommend changing into a fresh pair once you begin to feel damp.

Do they smell?

No.

Unlike traditional protection that lets leaks build up and cause unpleasant odours, Jack's Boxers Briefs are designed to resist odour.

Can I reuse them?

Yes.

Jack's ultra-absorbent incontinence boxer briefs are designed for long-term use, lasting on average 3 to 5 years.

Will this have a diaper effect?

I’ve handpicked every material to give you maximum comfort while feeling just like your everyday boxer briefs.

Which size should I choose?

Just follow my size chart and guide. I recommend picking your usual size, but if you’re unsure, go for the next one up.

And don’t worry — if it doesn’t fit perfectly, I’ll exchange it for free, even if you’ve already tried it on.

Why Jack?

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.

Washing and Use

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.

3. Do not tumble dry. Instead, air dry them to prolong their lifespan.

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!
