A single-use overall: it’s a special overall that reliably protect the wearer while working with biological and toxic fluids, pathogenic microflora. Disposable sterile overalls with a hood reliably protect clothes and the human body other than face, hands and feet. The ends of the pant and sleeves are rigged with rubber bands. There are 5 levels of protection. Each of those depends on the density of the nonwoven material used in the overalls manufacture.
