Fabric developer Polartec has launched a new air permeable laminate fabric, AirCore. The new fabric has a recycled face and back and is 100% free from per- and polyfluoroalkyl substances (PFAS).

Polartec said a combination of air permeability and its nano-fibre membrane can keep wearers dry while maintaining windproof and water repellency functionality. Business manager for Polartec and senior vice-president at parent group Milliken & Company, Ramesh Kesh, said traditional waterproof-breathable membranes rely on moisture vapour diffusion. AirCore, though, uses “a highly engineered nanofibre membrane technology to enable controlled airflow”.
