Recycled knits & Sustainable Basics
Upcycling industrially
Science based and sustainable design clothes since 2011

Fashion business is the world's most contaminating industry, even worse than transportation. The only one who can change this is YOU. Really? Yup. You don’t even need to consume less. No. Actually, a true hero consumes more… of waste. That's what we are here for! So that you could shop our planet waste-less. Isn't it controversial? Be it. We walk our talk. Our method is tested since 2011 by the founding mother of industrial upcycling, PhD Reet Aus. That's what we do. We upcycle industrially. 100%.
