A smoke hood is provided which is highly compact, quickly assembled, and light-weight. The device is defined by a tubular, transparent portion made from KAPTON, having a closed upper end and a lower skirt portion adapted to fit over at least the head of a user. A neck seal is attached to the interior of the tube and is designed to allow the user to quickly put on the hood without allowing any of the outside environment to flow into the hood. Inflow and outflow valves are attached to the hood the former of which connects to an air supply system. A method for assembling the hood is also provided along with details of an inflow valve arrangement, an outflow valve arrangement, and a kink-free air supply hose structure.
