Cotton & Chiffon, Triple Layer Facemask

Built in filter system. Shark print 100% cotton chambray with 2 layers of polyester-spandex chiffon. Triple layer, nose to chin coverage, white elastic ear-loops. Researh from U of Chicago stated "One layer of a tightly woven cotton sheet combined with two layers of polyester-spandex chiffon -- a sheer fabric often used in evening gowns -- filtered out the most aerosol particles (80-99%, depending on particle size), with performance close to that of an N95 mask material."
