All Seasons duvets bring you a soft comfortable barrier from the cold without the weighty mass of a traditional duvet, as it’s made with 90% small white goose feather and 10% down. This is a well-designed duvet with various tog combinations. The 4.5 tog duvet for Summer, the 9.0 tog for Spring/Autumn and combine the two duvets with the press stud fastening for maximum warmth during the winter. The opulent experience is further infused by the luxurious 232 thread count with 100% pure cotton cover; cassette stitched to keep the feathers evenly distributed. All edges are finished with high quality pipe edging.
