These DuPont chemical coveralls use Tyvek 500 Xpert fabric to provide effective protection against asbestos, biological hazards, water-based chemical liquid splashes, and both pharmaceutical and radioactive particulates. Tyvek fabric offers great breathability, allowing perspiration to escape while still providing a strong barrier against hazards. The ergonomic design allows wearers to move without feeling restricted, and features an innovative sleeve design that prevents sleeves from riding up even when working overhead. The hood has been designed to closely fit the contours of the face, while a larger zip pull makes it easier to put on and take off while wearing gloves.
