The ultimate guide to Undiemeister underwear

In underwear, perfection starts with what you don't see. Because the secret to true comfort starts with every detail, from fit to material. That's why we've put together this guide, so you know exactly which underwear best suits your body, your life and your preferences.

This underwear guide takes you through the main features of underwear to help you make a good choice. Such as the different models, as the classic boxer, a shorter sporty trunk, briefs or the loose fit, or loose boxer, for maximum freedom of movement: Undiemeister always has the right model. And of course, this guide will elaborate on the fabric, the unique Mellowood, which delivers maximum comfort and never sacrifices durability.

Mellowood is the basis of ultimate comfortable underwear.

Mellowood is silky soft, breathable and durable. Exclusively available at Undiemeister. Patented, from an innovative blend of TENCEL™ (Lyocell) and organic cotton, with a touch of elastane. Maximum sustainable production, combined with properties perfect for underwear:

  • Silk softness: softer than cotton, without sheen
  • Perfect temperature regulation: cool in summer, warm in winter
  • Optimal ventilation and moisture absorption: fresh, dry and hygienic all day long
  • Virtually no shrinkage or pilling
  • Colour retention, so underwear stays like new for a long time
  • GOTS-certified sustainability: produced with respect for people and planet

Where other brands choose conventional cotton or synthetic fibers, Undiemeister goes a step further. Mellowood combines luxury with responsibility, without concessions.

Which model suits you?

Choose comfort, without compromising on style. Undiemeister offers a choice of different models:

  1. Boxer briefs: The modern classic. The perfect middle ground between trunk and classic boxer, with slightly longer legs and a comfortable, brushed waistband. No chafing thanks to the extra fabric between the legs and made with few seams. At the back, where you sit, completely seam-free.
  2. Trunks: Shorter and sportier. Ideal for those who like a tight fit without excess material. Maximum freedom of movement, without sacrificing support.
  3. Briefs: Minimalist and functional. No legs, no creeping up material. For those who love absolute freedom and comfort.
  4. Loose Fits: Offer maximum freedom, with the loose legs.

All models have a maximum seamless finish and an ultra-soft inner waistband. Of course, all made from Mellowood.

Exclusive, natural colours

Undiemeister's colours are unique, and all inspired by nature. Each colour has a special name with a story and gives you a unique and exclusive look. You can choose from 13 colours, in a palette ranging from refreshing white to deep black.

The right size makes the difference

A perfect fit starts with accuracy. Underwear should be tight, but should never pinch. Too big a size will lump, too small a size will cause friction. Use the detailed size charts and fitting tips on the product page of each item. So you can find your ideal fit.

Washing advice so your underwear stays like new

Take good care of your Mellowood, then it will take good care of you. Follow the instructions below and your underwear will last for years:

  • Wash at 30°C maximum, preferably with similar colours
  • Do not use fabric softener, so the fiber structure is not affected
  • Air dry, simply over a clothes rack, or on a low temperature in the dryer
  • Use a laundry bag to minimize wear and tear

The natural antibacterial properties of TENCEL™ keep your underwear fresh, even with heavy use.

With underwear from Undiemeister, you wear maximum comfort, without compromise.

Frequently asked questions about underwear

What is the difference between a trunk and boxer shorts?

This is due to the unique combination of TENCEL™ with organic cotton and the optimally sustainable way in which both fabrics are produced. Recycling is of paramount importance here, throwing away as little as possible and striving for CO2 neutrality. As a result, we are also surpassing bamboo boxer shorts (and we should know!).

Why is underwear from Mellowood better?

Where does Mellowood come from?

Do Undiemeister's boxer shorts have a special waistband?
