Devon Duvets Extra Warm British Wool Duvet (900gsm)

Devon Duvets fills its Extra Warm duvet with 900gsm of certified British wool, giving a warmth level the maker rates at a 14+ tog equivalent, in a 260 thread count cotton casing and handcrafted in Devon with minimal stitching for drape. Wool's appeal for winter is that it insulates while wicking moisture and releasing excess heat, so it is the pick we would point overheating or menopausal sleepers to over lofty down, which is why it earns the hot-sleeper award despite a higher price than the synthetics. It is naturally hypoallergenic, carries a five-year makers guarantee and can be washed on a 30°C wool cycle, though it must be air dried rather than tumble dried and is heavier than down. Against the down picks it trades that airy, cloud-like loft for steadier temperature control, and it is the least cheap-to-run choice here.
