What is slim fit underwear?

Slim fit underwear is designed for men who want to move freely without compromising on style or comfort. The underwear fits closely without pinching. It follows your body, supports where needed and stays in place, all day long.

Why choose slim fit?

  • No excess fabric, no creases under your clothes.
  • Perfect support without pressure points.
  • Stylish, modern look even when your clothes come off.
  • Sweat-regulating and breathable, ideal for any activity.

Whether you're on the go, in the office or relaxing at home, slim fit underwear is your foundation for every day.

What makes our slim fit collection unique?

We believe underwear should do more than just "fit." It should be an experience. That's why we combine smart technology with refined craftsmanship:

1. Seamless comfort

Our slim fit models are strategically seamless. No abrasive stitching in crucial areas. Just a smooth, soft feel on your skin. No irritation or distraction.

Experience what "invisible underwear" really means.

2. Mellowood: our revolutionary fabric

We wanted the perfect fabric. So we just developed it ourselves.

Mellowood, a patented blend of:

  • 68% TENCEL™ Modal
  • 28% Organic cotton
  • 4% Elastane

This blend provides:

  • Temperature regulation warm in winter, cool in summer
  • Ultimate softness softer than cotton, even after many washes
  • Colour fastness even after dozens of washes
  • Antibacterial properties naturally fresh

3. No inner tags

We've removed all inner tags. Because who wants an itch from a label that's running around poking? Instead, all washing instructions and measurements are subtly printed on the inside of the fabric. Invisible to the eye, palpable in comfort.

4. Made in Europe. CO₂-neutral

At Undiemeister, we believe that true luxury is sustainable. That's why we produce all our underpants in Europe, under fair conditions and CO₂-neutral.

Close to home, transparent and with respect for people and planet.

Temperature-regulating and breathable

Slim fit men's underwear should not only fit well, it should cooperate with your body.

Mellowood keeps you cool when it's hot and warm when it's cold. Thanks to the open fiber structure of TENCEL™ Modal, the fabric is tremendously breathable. No sweat patches. No stickiness. Only fresh comfort.

Colourfast

What good is beautiful underwear if it fades after five washes?

Our Mellowood fabric retains its colour, wash after wash. Choose classic black, timeless navy or fresh white, your boxer briefs, slips or trunks will stay looking like new.

Label-free = Irritation-free

Comfort is in the details. And so we've tackled the biggest annoyance: itchy labels.

No more inner tags. No scissors needed. No frustration. Just, pure softness.

From sustainable fibers to eco-friendly packaging. Undiemeister underwear is designed with a green heart. Our carbon-neutral production and local manufacturing in Europe ensure minimal impact and maximum responsibility.
