Abstract
Abstract A covering such as a suit, glove, condom or sheath forming a chemical barrier against harmful agents. The covering is flexible, stretchable, and relatively thin, and includes at least one relatively thin chemical barrier that will neutralize the harmful characteristics of the harmful agents. If an object cuts through the covering and into a person's skin or if a harmful agent tries to traverse through the covering, the chemical barrier will neutralize the harmful characteristics of the harmful agent so that the agent is neutralized either before reaching the person's skin, after reaching the person's skin, or both. Various methods of making the covering are also disclosed.
