Sustainability Edition: Stylish on the move: Our slider cap with recycled fibre content has what it takes to become your absolute favourite accessory! We have used wool yarn from recycled and colour-assorted wool garments for this hat. The recycled wool is mixed with polyamide and silk, which gives the yarn stability and creates a colourful "tweed effect". It adapts perfectly to the shape of your head, completes your outfit and keeps you warm on cooler days. Must Have!
