Abstract
A self warming mask is disclosed. The self warming mask includes a facing layer configured to cover at least a portion of a person's face. Attached to the facing layer is at least one thermal delivery pad. The thermal delivery pad contains an exothermic composition. Once the mask is removed from a sealed package, air contacts the thermal delivery pad causing the mask to elevate in temperature . The thermal delivery pad can be constructed so that the rise of temperature and the length of time the mask remains heated is carefully controlled. The mask product can be used in combination with a fragrance or vapor delivery device for also releasing a fragrance, a vapor, or both as the mask is heated. In one embodiment, the fragrance or vapor delivery device can be attached and removed to the mask as a user desires.
