The Quallofil-Air 4 Seasons Duvet combines two separate duvets — a 175g/m² summer layer and a 300g/m² mid-season layer — that fasten together with ties to form a heavier winter duvet. Both layers are filled with extra-fine silicon hollow fibres in 100% polyester, allowing air to circulate freely while minimising moisture retention. The 100% cotton cover features cotton taped edging and discontinuous stitching for added durability. An Allerban treatment provides anti-bacterial, anti-fungal, and anti-dust mite protection, and both layers are machine washable at 40°C with tumble drying at a low temperature.
