Or 13.5 Tog Goose Feather & Down Duvet - 4 Sizes | Wowcher

Cosy winter duvet: Packed with the perfect mix of real goose feathers and fluffy natural down, it's designed to keep things snug without weighing you down.

Feather-light: Filled with 85% goose feathers and 15% down with a cambric cotton cover, it's just the right balance of soft and supportive. Sizes: Available in single, double, king, and superking to fit every bed—and every snuggler.
