Abstract: A headgear garment has pockets for receiving exothermic heat packets to provide an active heat-generating source proximate to the ears of a wearer. The garment includes a garment body having pockets for receiving exothermic heat-generating packets and a means for securing the garment to the wearer's head. The securing means may be the structural configuration of the garment itself. The pockets are constructed of a breathable material to allow the exothermic heat-generating packets to provide heat and are placed proximate to the wearer's ears when worn. An insulation material is placed between the pockets and the ears to protect the ears from any excess heat generated by the exothermic packets. The shown embodiments include earmuffs, headbands, including a helmet headband and a straight headband, and a hat.
