Experience cloud-like comfort with these bamboo pillowcases that are made from luxuriously soft bamboo-viscose fabric. So incredibly soft and comfortable, you’ll want to sleep on nothing but bamboo. Our bamboo pillowcases are naturally lightweight and breathable, and are twice as soft as cotton. Each set includes two pillowcases. Wash in cold and tumble dry on low heat.
