"Designed for flexible comfort through the year, the Homescapes Luxury White Duck Down All Seasons Duvet set pairs two duvets in one adaptable system. Use the 4.5 tog duvet for warmer nights, switch to the 9 tog duvet when temperatures drop, or fasten them together to create a 13.5 tog option for winter. Discreet plastic fasteners and buttonholes along the seams make it easy to adjust your bedding as the seasons change. Each duvet is filled with a blend of 60% white duck down and 40% white duck feather, offering natural insulation with a soft, lightweight feel. The cover is made from 100% down-proof cotton with a 330 thread count, helping to keep the filling securely contained while remaining breathable. A baffle box construction supports even air circulation to maintain consistent warmth across the duvet.
