M&S Smart Wash & Dry 13.5 Tog All Seasons 3-in-1 Duvet White

Built for extra warmth, this 13.5 tog duvet is will keep you comfortable in every season. An insulating filling provides cosy comfort without feeling heavy and the soft outer is finished with subtle striped detailing for a clean look. Its all-season design includes two breathable layers. Choose the 4.5 tog layer for summer sleeping or switch to the 9 tog option for cooler nights. When the coldest weather arrives, you can fasten the pieces together with the handy poppers for 13.5 tog warmth. Part of the Smart Wash & Dry collection (formerly Supremely Washable), the quick-dry design means it's ready to use again in no time after washing.
