For warmth under the covers, pure, natural white goose down is second to none. While Tilney functions as a down blanket, it can also serve as a an ultra-light duvet insert. 

Machine wash cold water on gentle cycle. Do not use a washing machine with an agitator. Do not use bleach (bleaching may weaken fabric and cause yellowing). Do not use fabric softener. Tumble dry on low heat using tennis balls in the dryer to help un-clump the down clusters.
