This Slumberdown Wonderful Wool Duvet is filled with 100% British wool. Wool fibre is incredibly complex and made up of lots of different layers which create pockets that trap air and help to circulate heat, enhancing insulation and warmth.
I already have a wool duvet and although warm I was missing the weight during the colder nights.
I let the duvet air and as soon as it went on the bed, super cozy, warm and slept incredibly well.
Highly recommended and one of my friends has already purchased on my recommendation
