Materials Lists.

Here you can find our preferred, accepted and prohibited materials lists. These lists guide us to create collections that are as long-lasting and sustainable as possible.  

With a minimum 96% of each collection our materials are either upcycled, recycled or made of deadstock. All our materials are being sourced locally or in Europe (mainly in Spain, Garmany, France and the UK). The upcycling process is taking place at our in-house production and forms part of our intuitive design process while creating unique fabrics with a strict zero-waste production. The tiniest leftover scraps are being used to create new out of old materials. If dyes are made, we only dye with natural dyes. 

96-100% of our garments in each of our collections are made from upcycled or deadstock materials. For smaller hardware/ trims which cannot be found in second hand stores we purchase from local suppliers, otherwise about 70% of our trims in our collections are upcycled.

The materials we mainly use are upcycled leather, upcycled wool, upcycled cotton, recycled polyester, upcycled lace, upcycled & deadstock silk, upcycled linen, upcycled mesh, upcycled polyamide, upcycled viscose, upcycled acetate, upcycled cupro.

For our latest collection in 2023 we used 50% cotton, 20% silk, 20% polyamide, and 10% viscose.

Preferred Materials 

  • Upcycled materials

  • Deadstock materials

  • Recycled materials

  • Regenerated materials of recycled origin

  • More sustainable regenerated materials such as EcoVero™, Lyocell or Tencel™

  • GOTS certified organic materials

  • Monomaterials, as they are more easily recycled as mixed materials

  • Naturally dyed or printed materials

  • Other certified sustainable materials

  • Vegetable tanned leather

 

Accepted Materials

  • Plant based materials such as cotton or linen

  • Regenerated cellulose based materials such as viscose or modal

  • Mixed materials that are 100% cellulose based

  • Materials made from animal fibers such as wool and silk

  • Leather & shearling tanned in the EU and bred for food production

 

Prohibited Materials

In our prohibited materials list we have also included most virgin materials as we focus on using only upcycled or deadstock materials. The list contains especially virgin materials which are slow to decompose, use mainly chemical in manufacture, fossil fuel based, or non-renewable. 

  • Fur

  • Angora wool

  • Mulesed wool

  • Exotic skins/ animal leather

  • Leather tanned outside the EU

  • Non-RDS Down

  • Polyurethane

  • Virgin Polyamide

  • Virgin Elastane

  • Uncertified Virgin Wool

  • Virgin Neoprene

  • Virgin Aramid

  • Virgin Polyethylene

  • Virgin PVA

  • Virgin Polyurethane

  • Any material not in accordance with the requirements of the EU REACH Directive.  

TYPES OF FIBERS EXPLAINED

Plant Fibers: Generally cellulose based natural fibers that are derived from the stems, leaves, seeds or fruits of different plants, like cotton, linen, hemp, jute, and sisal, come from plant parts such as stems, leaves, seeds, or fruits.

Animal Fibers: Natural protein based fibers, collected from mammals, insects, and mollusks, these protein-based fibers include lambswool, cashmere, mohair, alpaca, camel, and silk.

Regenerated Fibers: Artificial fibers, derived from plant cellulose, are transformed into yarn. Common examples include viscose, lyocell, cupro, modal, acetate, and triacetate.

Synthetic Fibers: Oil-based, man-made fibers, produced through chemical synthesis. Popular synthetic fibers include polyester, polyamide (Nylon), polyurethane, acrylic, and elastane.

Please be aware that the information on this page is continuously evolving. We consistently update and refine our lists of preferred and prohibited materials by conducting ongoing research and consulting with industry experts to ensure we have the latest information available.
