Abstract
The present application relates to an insulation pack in a wearable article, such as a footwear article. In one example embodiment, the insulation pack includes a perforated air retention and communication layer, an insulating compressible layer, and a reflective layer. In a compressed state, when the wearable article is worn by a wearer, the perforated air retention and communication layer and the insulating compressible layer maintain a lofted air space which is in air communication with an inner body space of the wearable article and acts as an insulating layer. Further, the reflective layer reflects radiated body heat. Thus, the insulation pack may provide a heat retention and insulation system for the wearable article by reducing body heat lost via radiation and conduction.
