About the KLØJO Boxershort

Are you done with those stains in your pants after urinating? The KLØJO boxer is designed to solve exactly that problem. 

Your KLØJO captures all residual drops and prevents them from reaching the outer fabric (and your pants). Giving you quiet, everyday confidence. 

Product details

KLØJO looks like premium everyday underwear but includes a discreet integrated protection layer. The thin inner layer absorbs residual drops and prevents them from reaching the outer fabric.

What it's made of

✅ Boxer: Premium OEKO-TEX® Standard 100 certified stretch cotton
✅ Protective layer: Waterproof and breahtable PUL combined with viscose

That's it. 

How to take care for your KLØJO

To make your KLØJO last for as long as possible.

Bart, 30 - 40

"I was done with worrying about drops coming through after visiting the toilet. Now with this boxer, I don't have to anymore. Thanks!"

M

Markus, 40 - 50

"Boxer feels really good and solves the annoying issue. When it's not in my drawer, I genuinly miss it. Going back to regular underwear just feels like a downgrade."

C

Chris, 40 - 50

"Was skeptical at first. Thought it would feel thick or medical like a diaper or incontinence wear. But it's surprisingly lightweight and just feels like normal underwear."

M

Michel, 60 - 70

"I used to avoid certain trousers that made those spots visible and double-checked more often than I liked. When I wear a KLØJO, I don't really think about it anymore."

S

Sven, 40 - 50 

"I tried the exercises and lifestyle changes my doctor advised. But it didn't help consistently. This feels like an extra reassurance."

"A well-made boxer that genuinely makes a difference to my confidence. Would love to see more colours in the future"

FAQ

Frequently asked questions

How does the KLØJO protection work?

In the crotch area of the boxer shorts, we've integrated an ultra-thin layer made from PUL and viscose. This combination is designed to be waterproof, breathable, and flexible at the same time. The result is discreet protection without bulk or stiffness. 

Does it work all day or do I need to change?

No you don't have to change during the day. At night, just put it into your laundy basket. 

Will KLØJO change the fit of my trousers?

No. It really is the same as regular premium underwear and has a great fit. 

Can I put the KLØJO boxer shorts in the washing machine?

Absolutely. KLØJO is designed for everday wear and regular machine washing. The materials are selected to maintain performance, comfort, and shape over time. For best results and long-lasting quality, simply follow the care instructions on the label. 

What size should I choose?

KLØJO boxer briefs follow standard premium sizing. If you usually wear a certain size in other premium brands, you can expect a similar fit here. 

Because the fit is slighly slim, if you are between two sizes, we recommend choosing the larger one. 

If you are unsure, have remarks or feel your size is missing, let us know. We continuously improve based on real feedback and want to get the fit exactly right. 

How does shipping work?

We ship from our warehouse in The Netherlands. After we've packed your order, you will receive a track & trace link. 
Usually in the EU it takes a couple of days until you received your order. 

How is KLØJO different from other leakproof brands?

KLØJO is designed with a different focus. Many leakproof products on the market are built for larger volumes or full incontinence, often resulting in thicker materials, bulkier construction and a more medical look and feel. 

KLØJO is created specifically for the everyday issue of post-micturition dribbling, a small but high-impact concern. KLØJO creates confidence wear.

Is KLØJO incontinence underwear?

No, it is not incontinence wear. We have designed KLØJO to protect against drops after peeing. See our video's to see if it is sufficient for your case. 

Are these boxers for old men?

Absolutely not. Dribbles after peeing is something that happens for many adult men. 
Did you know most of our customers are actually in their late 30's, early 40's?

Is it warm in the summer or during sports?

No, the KLØJO boxer short is made from breathable materials. So you don't have to worry during the hot summers or during your workout. 

Will the boxer shorts smell or stay wet?

No. The integrated layer is breathable, so it does not trap moisture the way thicker protective products might. Small drops are absorbed and spread within the fabric, allowing them to dry naturally. 
At all times, the outside stays dry.

Are the boxer shorts really handmade?

Yes. KLØJO started as a personal solution. In the beginning, we literally hand-sewed protective layers into our own boxer shorts to test what actually worked. 

Today, production has evolved into a structured process using our professional sewing machines, but it is still done in small batched with hands-on crafmanship. 

We consciously chose local manufacturing over overseas mass production. That means we stay close to the process, keep improving the details and maintain control over quality.

Small-scale production can come with some variations, but we see that as part of honest craftmanship, not mass factory output. 

Will more colours come up?

Absolutely, we are working on the design and production of new designs. Follow us on our socials or subscribe to our mailing-list to keep up to date. 

What is your return policy?

We understand that ordering underwear online requires trust. For hygiene reasons, we cannot accept returns of worns or used items. 

If you experience sizing issues or a defect, please contact us within 14 days after you received your order. We are a small team and stand behind what we make. If something is not right, we will make it right.
