Iconic British fashion label Paul Smith has announced that it will ban all exotic skins in future collections—including kangaroo skin, or “K leather.”

Kangaroo skin is a particularly light leather, making it a popular choice for luxury fashion items. Paul Smith recently updated its sustainability policies to include exotic skins and confirmed that this included K leather.

“Paul Smith is committed to ensuring high standards of animal welfare and requires this same commitment from all of our suppliers,” says the brand. “We do not use exotic skins, fur or Angora rabbit hair. We also do not use species listed in the CITES Appendices – a list of internationally protected animals.”
