Abstract

A puffer jacket configured to provide improved temperature regulation through graduated venting. In one embodiment, the jacket includes a back panel with baffles and insulation arranged to provide reduced insulation and increased venting of heat and humidity toward the center of the back. The back panel may include an alternating arrangement of insulation baffles (containing insulation) and vent baffles (free of insulation). The insulation baffles and vent baffles may be formed by joining inner and outer layers of fabric with laterally extending lines of stitching. The lines of stitching may follow paths selected to progressively change the relative size of the vent baffles and the insulation baffles toward the center of the back. For example, the lines of stitching may give the insulation baffles a somewhat hourglass shape shortening toward the center of the back resulting in increasingly greater venting of heat and humidity toward the center of the back.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. An item of outerwear comprising:
a front panel and a back panel, the back panel having:
an outer layer of fabric;
an inner layer of fabric; and
a plurality of lines of stitching extending across the outer layer and the inner layer, the plurality of lines of stitching joining the inner layer and the outer layer to define a plurality of baffles, a first plurality of the baffles including insulation to form a plurality of insulation baffles, a second plurality of the baffles being free of insulation to form a plurality of vent baffles, the insulation baffles and the vent baffles being arranged in an alternating pattern, each of the insulation baffles having a height and each of the vent baffles having a height, and wherein the lines of stitching forming the vent baffles and the insulation baffles are arranged in a non-parallel pattern to provide variations in the height of the insulation baffles and the vent baffles in inverse proportion across the back panel, such that when the height of the insulation baffles increases, the height of the vent baffles decreases, and when the height of the insulation baffles decreases, the height of the vent baffles increases, the variations in the height of the insulation baffles and the vent baffles providing the back panel with graduated venting properties; and
wherein the height of the insulation baffles is reduced toward a lateral center of the back panel and the height of the vent baffles is increased toward the lateral center of the back panel.

2. The item of outerwear of claim 1 wherein a single line of stitching extends between each pair of adjacent insulation baffles and vent baffles.

3. The item of outerwear of claim 1 wherein each insulation baffle is defined by an adjacent pair of the lines of stitching, the adjacent pair of the lines of stitching undulating toward one another toward the lateral center of the back panel.

4. The item of outerwear of claim 3 wherein each vent baffle is defined by the lines of stitching of adjacent insulation baffles.

5. The item of outerwear of claim 4 wherein each insulation baffle has a narrow region toward the lateral center of the back panel.

6. An item of outerwear comprising:
a plurality of panels joined in a shape configured to clothe at least a portion of a wearer's upper body, the plurality of panels including a back panel positioned to cover at least a portion of the wearer's back; and
wherein the back panel includes a plurality of laterally extending baffles, each of the baffles defining an internal void, the plurality of baffles including a plurality of insulation baffles with insulation disposed in each respective void of the plurality of insulation baffles and a plurality of vent baffles free of insulation in each respective void of the plurality of vent baffles, the insulation baffles and the vent baffles being arranged in an alternating pattern, each insulation baffle and each vent baffle having a height, the height of the insulation baffles and the height of the vent baffles varying inversely in proportion across the back panel, such that when the height of the insulation baffles increases, the height of the vent baffles decreases, and when the height of the insulation baffles decreases, the height of the vent baffles increases, the variations in the height of the insulation baffles and the vent baffles providing the back panel with graduated venting properties; and
wherein the back panel has a lateral center and the vent baffles increase in height toward the lateral center to reduce the insulation of the back panel in the lateral center.

7. The item of outerwear of claim 6 wherein each insulation baffle is separated from an adjacent vent baffle by a line of stitching.

8. The item of outerwear of claim 7 wherein the insulation baffles decrease in height toward the lateral center.

9. The item of outerwear of claim 8 wherein the back panel includes an inner layer, an outer layer and a plurality of laterally extending lines of stitching, the lines of stitching joining the inner layer and the outer layer to define the baffles.

10. The item of outerwear of claim 9 wherein each adjacent pair of the lines of stitching defines an insulation baffle of the plurality of insulation baffles or a vent baffle of the plurality of vent baffles.

11. The item of outerwear of claim 10 wherein each adjacent pair of the lines of stitching undulates toward or away from one another toward the lateral center of the back panel.

12. The item of outerwear of claim 11 wherein the insulation baffles and the vent baffles alternate in a regular repeating pattern over the entire height of the back panel.
