Rest your head on the natural softness and support of responsibly sourced down. Encased in pure, down-proof organic cotton, this light and lofty fill feels fluffy and full, with support that will gently compress under the weight of your head. We recommend this high performance pillow for stomach and side sleepers, as well as back sleepers who like more support under the neck. The warmest of our down duvet inserts, the Winter Weight is soft and lofty—will keep you toasty even on the coldest nights. This comfy layer is made with pure down encased in a down-proof, 100% organic cotton shell. Stitch-through box construction keeps the fill evenly distributed, so you stay perfectly warm right down to your toes. It’s filled with the same 600-fill-power down as our Three Season duvet, but with added fill to keep you in comfort.
