Introducing the Natori™ Feathers Essentials Pajama Set! Soft as a feather, the jersey knit has a hint of spandex for a nice drape that won't cling. Made with EcoVero™viscose. A fabrication made from renewable wood that is certified as a raw material, so that natural resources are not overexploited, and has a lower environmental impact compared to generic viscose. Lace is made from recycled spandex that was created as a by-product in the manufacturing process. Fabrication is soft and feather-light. The set includes a comfortable tee and pull-on pants.
