Our Purpose

Positive Fibers

We are on a mission to put the ECO into eCommerce 1 positive product at a time.

Nearly 10% of the annual global carbon budget is consumed by the fashion industry. However, fashion is here to stay. It is the way we express ourselves and how we connect with others. Therefore it's time to rethink the supply chains, starting with the core ingredients: fibers.

At Positive Fibers we believe that fashion can be an effective catalyst for positive change, a global circular economy that meets the needs of the people within the means of the planet. We work towards this with one positive product at a time.


Our Worldview

Fashion Model in Trench Coat


We seek to put the ECO into ecommerce one positive product at a time. We are mobilizing everyone who wears clothes to make bio-circular™ fashion the status quo.


What if our clothes were completely compostable at the end of their lifecycle? We believe that the future of fashion is regenerative so nature can take a breather.
