Abstract: The trash bag raincoat is made of substantially waterproof material, having sufficient length to enclose at least the shoulder, torso and back areas of a person of a predetermined height and size range. Preferably, the trash bag raincoat includes a hood extendable from an opening along the bottom of the bag and sleeves extendable from openings in the side edges of the bag. The openings are equipped with re-sealable fasteners, so that the hood and sleeves are tucked inside the bag with the openings sealed by the fasteners for use as a trash bag. When the openings are unsealed a person can withdraw the hood and sleeve elements and wear the trash bag upside down while placing the wearer's arms through the side openings into the sleeves and placing the wearer's head through the unsealed bottom opening into the hood, thus providing rain protection for the wearer.
