Crafted from 100% brushed microfiber, features a naturally breathable fabric that offers lightweight, year-round comfort—perfect for all seasons and hot sleepers. Through the brushed process, a fine and fluffy layer of fibers is formed on the surface of the fabric, presenting a velvet-like texture. This provides an excellent skin-contacting experience and reduces friction and irritation. Designed with an envelope closure for easy use and a secure fit to keep your pillow in place.
