Abstract
Abstract A firefighter's coat has a body section and a collar section, each of these sections has an outer layer and an inner layer and an intermediate moisture barrier layer. The intermediate moisture barrier layer is waterproof to prevent moisture flow therethrough, and the intermediate moisture barrier layer is also attached to at least one of the other layers to provide stability among the layers.
