Sustainability & Care


ECONYL® is a high performance nylon yarn made from recycled ocean plastics, disused fishing nets and landfill waste. After capturing this waste, the nylon is broken down and reformed into new fibres that are chemically identical to brand new nylon. As well as reducing emissions by 90%, it can be recycled infinitely – infinitely!
