Zoned insulation garment

Abstract

Aspects herein relate to a garment having zoned insulation features. The zoned insulation features comprise projections that extend in the z-direction with respect to the surface of a base material forming the garment such that the projections face toward a body surface of a wearer when the garment is worn. The number and/or size of the projections may vary over the garment depending on the amount of insulation needed in different areas of the garment.

What is claimed is: 
     
         1 . A zoned insulation garment comprising:
 a backer material that forms an outer-facing surface of the zoned insulation garment; and   a base material having a first surface and an opposite second surface, the second surface of the base material secured to the backer material, the first surface of the base material forming an inner-facing surface of the zoned insulation garment, the base material forming:
 a first garment portion having a first plurality of projections that extend from the first surface of the base material, each of the first plurality of projections having terminal ends located opposite the base material, and 
 a second garment portion having a second plurality of projections that extend from the first surface of the base material, each of the second plurality of projections having terminal ends located opposite the base material, wherein an entirety of the terminal ends of the each of the first plurality of projections have a greater surface area than an entirety of the terminal ends of the each of the second plurality of projections. 
   
     
     
         2 . The zoned insulation garment of  claim 1 , wherein the first plurality of projections are located adjacent to each other in a tessellation pattern. 
     
     
         3 . The zoned insulation garment of  claim 2 , wherein spaces are defined between adjacent projections of the first plurality of projections. 
     
     
         4 . The zoned insulation garment of  claim 1 , wherein the second plurality of projections are located adjacent to each other in a tessellation pattern. 
     
     
         5 . The zoned insulation garment of  claim 4 , wherein spaces are defined between adjacent projections of the second plurality of projections. 
     
     
         6 . The zoned insulation garment of  claim 1 , wherein the base material is formed at least partially from a yarn having Far Infra-Red (FIR) fibers. 
     
     
         7 . The zoned insulation garment of  claim 1 , wherein the base material is formed at least partially from a hollow core yarn. 
     
     
         8 . The zoned insulation garment of  claim 7 , wherein the hollow core yarn is plaited with an additional yarn. 
     
     
         9 . The zoned insulation garment of  claim 1 , wherein the zoned insulation garment comprises at least:
 a torso portion having a front area, a back area, and a pair of side areas; and   a pair of sleeve portions extending from the torso portion of the zoned insulation garment.   
     
     
         10 . The zoned insulation garment of  claim 9 , wherein the pair of side areas of the torso portion are formed from the first garment portion, and wherein the pair of sleeve portions are formed from the second garment portion. 
     
     
         11 . A zoned insulation garment comprising:
 a backer material that forms an outer-facing surface of the zoned insulation garment; and   a base material having a first surface and an opposite second surface, the second surface of the base material secured to the backer material, the first surface of the base material forming an inner-facing surface of the zoned insulation garment, the base material forming:
 a first garment portion having a first plurality of projections that extend from the first surface of the base material, each of the first plurality of projections having terminal ends located opposite the base material, 
 a second garment portion having a second plurality of projections that extend from the first surface of the base material, each of the second plurality of projections having terminal ends located opposite the base material, wherein an entirety of the terminal ends of the each of the first plurality of projections have a greater surface area than an entirety of the terminal ends of the each of the second plurality of projections, and 
 a third garment portion having a third plurality of projections that extend from the first surface of the base material, each of the third plurality of projections terminating in one or more edges. 
   
     
     
         12 . The zoned insulation garment of  claim 11 , wherein the one or more edges of the third plurality of projections are interconnected to one another to form a tessellation pattern. 
     
     
         13 . The zoned insulation garment of  claim 11 , wherein the each of the third plurality of projections defines a space formed from the first surface of the base material. 
     
     
         14 . The zoned insulation garment of  claim 11 , wherein the zoned insulation garment comprises at least:
 a torso portion having a front area, a back area, and a pair of side areas; and   a pair of sleeve portions extending from the torso portion of the zoned insulation garment.   
     
     
         15 . The zoned insulation garment of  claim 14 , wherein the pair of side areas of the torso portion are formed from the first garment portion, wherein the pair of sleeve portions are formed from the second garment portion, and wherein a central back area is formed from the third garment portion. 
     
     
         16 . The zoned insulation garment of  claim 11 , wherein the base material is formed at least partially from a yarn having Far Infra-Red (FIR) fibers. 
     
     
         17 . The zoned insulation garment of  claim 11 , wherein the base material is formed at least partially from a hollow core yarn. 
     
     
         18 . The zoned insulation garment of  claim 17 , wherein the hollow core yarn is plaited with an additional yarn. 
     
     
         19 . A zoned insulation garment comprising:
 a backer material that forms an outer-facing surface of the zoned insulation garment; and   a base material having a first surface and an opposite second surface, the second surface of the base material secured to the backer material, the first surface of the base material forming an inner-facing surface of the zoned insulation garment, the base material forming:
 a first garment portion having a first plurality of projections that extend from the first surface of the base material, each of the first plurality of projections having terminal ends located opposite the base material, and 
 a third garment portion having a third plurality of projections that extend from the first surface of the base material, each of the third plurality of projections terminating in one or more interconnected edges. 
   
     
     
         20 . The zoned insulation garment of  claim 19 , wherein the base material is formed at least partially from a yarn having Far Infra-Red (FIR) fibers or from a hollow core yarn.
