Abstract
A garment providing an emergency source of breathing gas is disclosed which utilizes small diameter tubing to form a reservoir for storage of high-pressure gas. A mask and pressure regulator attached to the reservoir enable a user to tap the stored gas. The tubing reservoir may be incorporated in the fabric of the garment, or retained between layers of the garment. A lightweight shielding layer protects the user against injury caused by accidental rupture of the high-pressure reservoir.
