Abstract
Abstract A heat shield insert to be worn between inner clothing and outer garments of a person is disclosed including a flexible insulator removeably received in a flexible fabric covering. The insulator in its preferred form includes first and second reflective layers sandwiching sealed, multiple air cell material. The reflective layers reflect body heat back and cold away from the person. The air encapsulated in the air cells acts as insulation in reducing heat transfer and provides a resilient, cushion type support. The heat shield insert has a shape corresponding to the torso and upper leg portions of the person and includes a rectangular portion for substantially covering the torso and first and second leg portions extending from and integral with the rectangular portion for covering the legs to adjacent the knees. The lower edge of the rectangular portion is supported on the crotch of the outer garment. The first and second leg portions extend in the pants leg and the rectangular portion extends in the outer garments for orientating the heat shield insert in the outer garments keeping the heat shield insert from tipping to one side on the crotch of the outer garment. The heat shield insert is flat, thin and flexible allowing the heat shield insert to conform to and bend with the body of the person without restricting movement and without detracting from the aesthetics of the outer garments.
