Metallized breathable composite fabric

A metallized breathable composite fabric for apparel comprising:

• an innermost fabric layer comprising a woven fabric, a knit fabric, or a non-woven fabric, the innermost fabric layer comprising a first inner surface and a first outer surface, the innermost fabric layer having a moisture vapor transmission rate of at least 500 g/m2/24 hr;
• a metallized membrane comprising:
• a second inner surface coupled to the first outer surface of the inner layer via first point contacts;
• and
• a second outer surface;
• the metallized membrane including a base layer containing a nanoporous polyolefin film, the base layer comprising the second inner surface and a third outer surface, wherein the base layer has a thickness of less than 50 microns, an infrared transparency of at least about 40% at a wavelength of approximately 9.5 microns, and a moisture vapor transmission rate of at least 500 g/m2/24 hr, the nanoporous polyolefin film having a reflectivity of at least 0.87 at a wavelength of approximately 9.5 microns,
• the metallized membrane including a metal layer, the metal layer comprising the second outer surface and a third inner surface, the third inner surface coupled to the third outer surface of the base layer, wherein the metal layer has a reflectivity of at least 0.76 at a wavelength of approximately 9.5 microns and a moisture vapor transmission rate of at least 500 g/m2/24 hr;
• and
• an outermost fabric layer comprising a knit of polyester fully drawn yarn (FDY), the outermost fabric layer having a cover factor of between 67 percent and 71 percent, the outermost fabric layer comprising a fourth outer surface and a fourth inner surface, the fourth inner surface coupled to the second outer surface of the metal layer of the metallized membrane via second point contacts, the outermost fabric layer having a moisture vapor transmission rate of at least 500 g/m2/24 hr.
