Global Recycled Standard

Where possible we’ve only use natural materials, but a key part of our sustainability strategy is to reuse materials that would have otherwise gone to waste. We use SEAQUAL YARN upcycled from marine plastic collected during ocean clean-ups. The upcycled polyester fibers meet the stringent requirement of the Global Recycled Standard which verifies and tracks recycled raw materials.
