About us

Some brands were born out of a good idea. Undiemeister was born out of a frustration.
Because why should underwear, something you wear every day, so often feel like an afterthought? Worn-out fits. Fabrics that breathe like plastic. Labels that itch. Models you'd rather hide than wear.

That had to change. Undiemeister began with a simple mission: to make undergarments that make sense. In comfort, style and in durability. And above all: in how it feels to wear. No mass production. No noise. Just smart choices, carefully executed.

How it began

We started small. Two men, one idea. With a background in textiles and an obsession with quality, we decided in 2019 to make ourselves what we couldn't find anywhere: underwear that fits like a glove, lasts for years and looks good.

We soon discovered that we were not alone in this.

The name Undiemeister was no coincidence. It is a wink, but also a statement. 'Undies' - the American word for underwear - combined with 'Meister', the German word for 'master'.
Not because we know everything. But because we strive for the highest achievable every day. In material selection, fit, production and durability. Always a little bit better. Always masterful.

Undiemeister became a brand that people not only attract but also trust.

From men to everyone

For the first few years, we focused exclusively on men's underwear. Boxer briefs, undershirts, socks. All designed with the same obsession for detail and wearing comfort. And with success. Our community grew. Customers came back. And with them also came one recurring question:

"When will there be something for women?"

The answer took a while. Not because we didn't want it. But because we wanted to do it right. Just as good as what we have been making for men for years.

In September 2025, we took the next step: the launch of our very first women's collection. A carefully curated line of underwear and tops, made from an innovative blend of TENCEL™ Modal, Coolmax and elastane, soft to the skin, kind to the planet and designed with exactly the same attention and conviction you've come to expect from us.

Not just any extension. An extension of our philosophy: quality is universal. And every body deserves the best.

Today

Today, Undiemeister is more than just underwear. It is a brand for people who feel the difference. Who know that comfort is in the details, and that sustainability goes beyond a label on the packaging.

We continue to grow. In offerings. In impact. In ideas.

And who knows what tomorrow will bring. One thing we know for sure: we keep building mastery. From the inside out.

Premium undergarments. Without compromise.

At Undiemeister, it's all about comfort, style and durability. No empty claims, but cleverly designed undergarments that last for years. Born from craftsmanship, developed with vision and carried by a team of Meisters who build the best underwear in the world every day.

Undiemeister's mission statement.

Always striving for top quality, always striving for the most durable. Ever since 2011, we have been busy building top quality sustainable underwear.

The first step of our journey

Underwear made of bamboo was the first step on our journey and a nice step forward compared to cotton. Both in sustainability and quality. From different companies, we convinced consumers to make a different choice. That was a very instructive period. But it can be better ... and it must be better.

If it can be done better, then do it

The journey is never finished. Good is not good enough for us. So if we can take a big step forward with premium quality and sustainability, of course we do it. Then you join hands and move forward together from different companies. Mellowood was the first big step forward. Frankly, the most beautiful fabric we have ever seen. And felt. Rightfully The Next Step. Multiple fabrics, all maximally comfortable and durable, followed. Want to know more not only about Undiemeister but also about our own Mellowood?

So who is Undiemeister?

Undiemeister is the result of an innovative collaboration between two pioneers from the underwear world: Rik Vegter and Jeroen Adriaans. Both have earned their spurs in the bamboo underwear segment.

• Rik Vegter was already active with bamboo underwear in 2011 and stood at the cradle of the first generations of sustainable basics.
• Jeroen Adriaans was the founder of Bamigo and built the brand into an international multi-million dollar company.
  

Yet they felt it could be even better. Even more durable. Even more comfortable. And so was born Mellowood: the patented fabric that forms the basis for all Undiemeister products. A clever mix of 68% TENCEL™ Modal, 28% organic cotton and 4% elastane, produced entirely carbon-neutral in Europe.

So Undiemeister is not a copy. It is a next step. A stylish brand for men who choose quality with a mission.

The latest Undiemeister TV commercial is live!

Do you know our first TV commercial? With the crazy moving, almost dancing men in little weird underwear? That one has been on television for three years and watched by millions. Yes, yes, time goes fast! So it's high time for something new. And that's easier said than done, because how do you top that?

Why that German text "Ich bin Undiemeister"?

Because we are a Dutch company! The reason for the German text is that we looked hard for what you call a "pay off" that includes our brand Undiemeister. And then it makes sense to turn that into a German phrase. Moreover, it is striking because many people will think "huh?". You might too! And finally: nice and short, so you can put it in almost anywhere. Besides, you are a Meister or you are not a Meister, that goes across all national borders!

We hope you like the spot and we wish you lots of wearing pleasure, Meister!
