a lining that is secured to the shell at a plurality of points to form a plurality of compartments; a thermally insulating filling contained within each of the plurality of compartments; and an outer layer disposed adjacent to the shell, wherein the outer layer overlays the plurality of points and the plurality of compartments while being detached from the plurality of points and the plurality of compartments. ### Claim 2 (depends on 1) The thermally insulated garment of claim 1, wherein one or more of the shell or lining comprise one or more heat management features. ### Claim 3 (depends on 2) The thermally insulated garment of claim 2, wherein the one or more heat management features comprise heat reflective features disposed upon the lining. ### Claim 4 (depends on 1) The thermally insulated garment of claim 1, wherein one or more of the outer layer, shell, or lining are water resistant or waterproof. ### Claim 5 (depends on 1) The thermally insulated garment of claim 1, wherein one or more of the outer layer, shell, or lining are breathable or at least partially gas permeable. ### Claim 6 (depends on 1) The thermally insulated garment of claim 1, wherein the outer layer is secured to at least the shell at an edge of the shell. ### Claim 7 A thermally insulated garment, comprising: a base quilt comprised of: a shell; a lining that is secured to the shell at a plurality of points to form a plurality of compartments; and a thermally insulating filling contained within each of the plurality of compartments; an outer layer disposed adjacent to the shell; and an inner layer disposed adjacent to the lining, wherein the outer layer and inner layer each overlay the plurality of points and the plurality of compartments while being detached from the plurality of points and the plurality of compartments. ### Claim 8 (depends on 7) The thermally insulated garment of claim 7, wherein one or more of the shell or lining comprise one or more heat management features. ### Claim 9 (depends on 8) The thermally insulated garment of claim 8, wherein the one or more heat management features comprise heat reflective features disposed upon the lining. ### Claim 10 (depends on 7) The thermally insulated garment of claim 7, wherein one or more of the outer layer, inner layer, shell, or lining are water resistant or waterproof. ### Claim 11 (depends on 7) The thermally insulated garment of claim 7, wherein one or more of the outer layer, inner layer, shell, or lining are breathable or at least partially gas permeable. ### Claim 12 (depends on 7) The thermally insulated garment of claim 7, wherein the outer layer and inner layer are each attached to the base quilt at an edge of the base quilt. ### Claim 13 (depends on 7) The thermally insulated garment of claim 7, wherein at least one of the outer layer, inner layer, shell, or lining are wind resistant. ### Claim 14 A method for assembling a thermally insulated garment, comprising: providing an inner liner and an outer shell; disposing an insulation layer between the inner liner and outer shell; selectively attaching the inner liner to the outer shell to create a base quilt with a plurality of compartments containing the insulation layer; disposing an outer layer over the outer shell; and attaching the outer layer to an edge of the base quilt. ### Claim 15 (depends on 14) The method of claim 14, wherein disposing the insulation layer between the inner liner and outer shell comprises: disposing the insulation layer atop the inner liner; disposing the outer shell atop the insulation layer; and selectively attaching the inner liner to the outer shell through the insulation layer. ### Claim 16 (depends on 14) The method of claim 14, wherein disposing the insulation layer between the inner liner and outer shell comprises inserting the insulation layer into each of the plurality of compartments after the inner liner is selectively attached to the outer shell. ### Claim 17 (depends on 14) The method of claim 14, wherein selectively attaching the inner liner to the outer shell comprises stitching the inner liner to the outer shell through the insulation layer. ### Claim 18 (depends on 14) The method of claim 14, further comprising disposing an inner layer of the inner shell, and attaching the inner layer to the edge of the base quilt.
