Note: No appropriate materials are listed here. Supply of traditional materials like non-woven polypropylenes are in short supply. The typical materials used to produce the gowns are either non-woven, synthetic material such as polypropylene, polyester, or, polyethylene or woven cotton or polyester (with a repellent finish applied if necessary). 

Fabrics that are low absorbent or hygroscopic and that are made from very thin and fine fibers, such as microfibers with irregular surfaces/cross-sections and shorter in length, are preferred. Please review more information about the fabrics used in these gowns.
