BedVoyage Bamboo Pillowcases are made from 100% bamboo viscose, are subtly cool and extremely breathable, with a feel softer to the touch than a 1,000 thread-count Pima cotton. The pillowcases will not pill nor fade. Bamboo is an easy care and durable fiber, and those with sensitive skin will benefit from the round bamboo fibers which are extremely smooth against the skin. Wash Separately in cold water; fabric softener is not recommended. A Chlorine free stain remover may be sprayed directly on stubborn stains. Bleach is not recommended. Tumble dry on low heat, remove immediately.
