Sustainable Materials

We only ever use natural fibres at Celtic & Co. because they are renewable, sustainable and a pleasure to wear. The pieces we design are thoughtfully crafted from yarns and fibres that are kind to people and the planet.


In our strive to improve on sustainable sourcing and production, we have incorporated this environmentally conscious fabric into some of our key lines for the new season.

Utilising on the longevity and strength offered by linen, Celtic & Co. have sought out how to further make our summer lines more sustainable and eco-friendly. Recycled linen provides all the beneficial properties of the material with an improved approach in reviving and reusing the fabric.

Leading the way in our Spring Summer collection, this plant-based fabric combines durability and supreme softness for functional style. Sourced from world renowned Lyocell producer Lenzing, the fabric offers breathable, water-absorbent properties for when those warmer season come around.

Here at Celtic & Co., we are thrilled to welcome this highly durable material in two of our key seasonal lines.
