1. A thermally adaptable insulating garment wearable by a user and configured to change between configurations based on at least one of body temperature of the user and temperature of an environment immediately external to the thermally adaptable insulating garment, the configurations including a lofting and flattening to provide for increased and decreased insulation provided by the thermally adaptable insulating garment based on the at least one of the body temperature of the user and the temperature of the environment immediately external to the thermally adaptable insulating garment, the thermally adaptable insulating garment comprising:
an adaptive material configured to assume a lofted configuration and a flat configuration in response to different temperatures, with the flat configuration occurring within a temperature range of 10-40° C., the adaptive material including:
an adaptive first textile layer including:
a plurality of twisted polymer coil actuators with a first thermal expansion coefficient with a magnitude of at least 1000 μm/m/K and an average spacing between twisted polymer coil actuators at least 100% of average diameter of the twisted polymer coil actuators, and
a second material disposed adjacent to the twisted polymer coil actuators, the second material having a second thermal expansion coefficient that is different from the first thermal expansion coefficient;
a second textile layer disposed opposing the adaptive first textile layer;
a plurality of linear engaging portions between the adaptive first textile layer and second textile layer; and
a plurality of elongated cavities defined by the first and second textile layers and respective adjacent pairs of the linear engaging portions, the plurality of elongated cavities generated while the adaptive material is at least in the lofted configuration, wherein the plurality of elongated cavities further comprise a plurality of additional layers extending within the plurality of elongated cavities and coupled to respective opposing sides of an internal face of a portion of the plurality of elongated cavities defined by the adaptive first textile layer.
