The Blue Ridge Siberian Down Pillow combines the softest premium materials to provide you with the most comfortable night's sleep you've ever experienced. It starts with peerless white pima cotton. Pima cotton is essentially "gourmet" cotton, made from longer, silkier individual cotton fibers for a premium feel that is both luxuriously soft and incredibly strong. But it's what's inside that counts, and inside this Pillow is hypoallegenic Siberian white down—among the finest available, offering higher loft and more trapped air. It's like sleeping on a cloud.
