ABSTRACT:
An article of clothing, particularly a glove, which is highly resistant to chemical warfare agents, comprising a fabric substrate, normally pre-shaped to form the article, which is coated with an inner layer of a resilient elastomer, such as natural rubber, deposited from a latex, which adheres to but does not penetrate the substrate, and then coated with an outer layer of a butyl rubber which may contain an inorganic filler. The fabric substrate provides wearer comfort while the combination of an inner layer having a high vapor retention capacity and an outer layer which is resistant to toxic chemicals in liquid form and has a low vapor permeability, provides a high resistance to toxic chemicals for periods of time not heretofore possible.
