         6 . The composite fabric according to  claim 1 , wherein the fabric shell has an air permeability of from 0 CFM to about 5 CFM when tested in accordance with ASTM D737. 
     
     
         7 . The composite fabric according to  claim 1 , wherein the fabric shell has an air permeability of from 0 CFM to about 2 CFM when tested in accordance with ASTM D737. 
     
     
         8 . The composite fabric according to  claim 1 , wherein the insulating material comprises a natural insulating material, a synthetic insulating material, or a combination thereof. 
     
     
         9 . The composite fabric according to  claim 8 , wherein the natural insulating material comprises down, cotton, wool or a combination thereof. 
     
     
         10 . The composite fabric according to  claim 8 , wherein the synthetic insulating material comprises polyester, polyethylene terephthalate, polypropylene, acrylic and combinations thereof. 
     
     
         11 . The composite fabric according to  claim 1 , wherein the plurality of spacers are strips of fabric. 
     
     
         12 . The composite fabric according to  claim 11 , wherein each of the plurality of insulating structures are retained against the first fabric layer by the fabric strips 
     
     
         13 . The composite fabric according to  claim 12 , wherein the plurality of fabric strips retain the plurality of insulating structures against the first fabric layer in a woven construction. 
     
     
         14 . The composite fabric according to  claim 1 , wherein each of the plurality of spacers is sized so that when the composite fabric is worn the plurality of insulating structures lie against and substantially overlap the plurality of spacers. 
     
     
         15 . The composite fabric according to  claim 1 , wherein each of the plurality of spacers is sized so that when the composite fabric is worn the plurality of insulating structures lie against and substantially cover the plurality of spacers.
