Our corovin duvets are made from a polypropylene outer fabric and filled with anti-allergenic hollowfibre. This hypoallergenic polypropylene outer is a non-woven fabric which is durable yet lightweight and represents great value for money, yet still ensuring comfort and warmth. These duvets are channel stitched to ensure the hollowfibre filling is secure and wont move to one particular area of the duvet, ensuring an even fill across the duvet. These duvets are machine washable and able to be tumble dried on a low heat setting. Our corovin duvets are available in tog ratings of 4.5 tog, 10.5 tog, 13.5 tog, and 15 tog and in single, double, king, and superking size.
