Our story

We couldn't find any underwear that was good enough. So we made our own fabric.

It all started in 2011 with a simple frustration: everyday underwear was either comfortable or sustainable, but rarely both. So we set out to find something better. When we couldn’t buy it, we made it ourselves.

Years of testing later, Mellowood was born: a perfect combination of TENCEL™ Modal and certified organic cotton. We patented the fabric, and to this day, you’ll find it exclusively at Undiemeister.

  • Patented Mellowood, available nowhere else
  • TENCEL™ Modal + certified organic cotton
  • Designed in Europe
