For year round comfort, featuring a 10.5 tog duvet for cooler climates & a 4.5 tog for warmer nights, this Fogarty duvet can be expertly designed to combine to create a 15 tog duvet for the coldest nights. Crafted with a super soft cotton cover & filled with white duck feather & duck down for fantastic cosy warmth without the weight, this duvet is machine washable & available in a choice of sizes. The high thread count casing of this product provides a natural barrier against bedbugs. Please Note: As feather is a natural product, a slight odour can be expected, that will disperse in use.
