The Kleenguard™'s three-layer fabric construction features a middle layer of porous film that allows heat and sweat vapor escape, yet protects against many dry particulates and liquids. Use during wet jobs in manufacturing plants, tank cleaning, liquid handling, rubber manufacturing and pressure washing. Garments have more fabric in key stress areas for a great range of motion. Coveralls passed ASTM F1670/1671 testing for penetration of blood, body fluids and blood-borne pathogens.
