The Quallofil Air 4 Season Duvet combines two separate duvets — a 175 g/m² summer layer and a 300 g/m² mid-season layer — that fasten together with ties for winter use. The filling consists of extra-fine silicon hollow fibres in 100% polyester, promoting air circulation and reducing moisture build-up while remaining ultra lightweight. The outer cover is made from 100% cotton percale with dash stitching throughout. The duvet is machine washable at 40°C and suitable for tumble drying at a low temperature.
