Abstract

Multi-climate sleeping bags and methods of making the same are described. One sleeping bag may comprise a bottom panel comprising a head end and a foot end, wherein the bottom panel is formed from an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell, a first top panel comprising an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell, a first fastening mechanism configured to detachably couple an edge of the first top panel to an edge of the bottom panel, a second top panel comprising an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell, and a second fastening mechanism configured to detachably couple an edge of the second top panel to the edge of the bottom panel.

First claim

What is claimed is:

1. A multi-climate sleeping bag comprising:
a bottom panel comprising a head end and a foot end disposed opposite the head end, the bottom panel further comprising a hood disposed adjacent the head end, wherein the bottom panel is formed from an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell;
a first top panel comprising an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell;
a first zipper fastening mechanism configured to detachably couple an edge of the first top panel to an edge of the bottom panel, wherein the first zipper fastening mechanism comprises a first pull configured to engage and couple a first slider path disposed along the edge of the bottom panel and a second slider path disposed along the edge of the first top panel; and
a second top panel comprising an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell; and
a second zipper fastening mechanism configured to detachably couple an edge of the second top panel to the edge of the bottom panel, wherein the second zipper fastening mechanism comprises a second pull configured to engage and couple a third slider path disposed along the edge of the bottom panel and a fourth slider path disposed along the edge of the second top panel,
wherein,
the first top panel is configured to be coupled to the bottom panel without the second top panel to define a sleeping compartment having a first climate zone comprising a limit rating of 35° F. and above, as measured using EN standard testing, wherein the second top panel is decoupled from the bottom panel to define the sleeping compartment having the first climate zone,
the second top panel is configured to be coupled to the bottom panel without the first top panel to define a sleeping compartment having a second climate zone comprising a limit rating of 20° F. and above, as measured using EN standard testing, wherein the first top panel is decoupled from the bottom panel to define the sleeping compartment having the second climate zone, and
both the first top panel and the second top panel are configured to be contemporaneously coupled to the bottom panel to define a sleeping compartment having a third climate zone comprising a limit rating of 5° F. and above, as measured using EN standard testing.

2. The multi-climate sleeping bag of claim 1 , further comprising a cord configured to constrict and/or expand an aperture at least partially defined by the hood.

3. The multi-climate sleeping bag of claim 1 , wherein the insulating material of the bottom panel comprises a down material, an offset quilted material, a shingled synthetic material, or a combination thereof.

4. The multi-climate sleeping bag of claim 1 , wherein the insulating material of the first top panel comprises a down material, an offset quilted material, a shingled synthetic material, or a combination thereof.

5. The multi-climate sleeping bag of claim 1 , wherein the insulating material of the second top panel comprises a down material, an offset quilted material, a shingled synthetic material, or a combination thereof.

6. The multi-climate sleeping bag of claim 1 , further comprising one or more flaps configured to couple the hood to one or more of the first top panel and the second top panel.

7. The multi-climate sleeping bag of claim 6 , wherein the flaps are configured to overlay at least a portion of the first, second, third, or fourth slider paths to secure one or more of the first pull and the second pull in a coupled position.

8. The multi-climate sleeping bag of claim 1 , further comprising a draft tube disposed adjacent the at least a portion of the second zipper fastening mechanism.

9. A multi-climate sleeping bag comprising:
a bottom panel comprising a head end and a foot end disposed opposite the head end, wherein the bottom panel is formed from an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell;
a first top panel;
a first fastener mechanism configured to detachably couple a portion of the first top panel to a portion of the bottom panel;
a second top panel comprising an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell; and
a second fastener mechanism configured to detachably couple a portion of the second top panel to a portion of the bottom panel,
wherein,
the first top panel is configured to be coupled to the bottom panel without the second top panel to define a sleeping compartment having a first climate zone, wherein the second top panel is decoupled from the bottom panel to define the sleeping compartment having the first zone,
the second top panel is configured to be coupled to the bottom panel without the first top panel to define a sleeping compartment having a second climate zone, wherein the first top panel is decoupled from the bottom panel to define the sleeping compartment having the second climate zone, and
both the first top panel and the second top panel are configured to be contemporaneously coupled to the bottom panel to define a sleeping compartment having a third climate zone, wherein each of the first, second, and third climate zones have a different limit rating as measured using EN standard testing.

10. The multi-climate sleeping bag of claim 9 , wherein the bottom panel further comprising a hood disposed adjacent the head end.

11. The multi-climate sleeping bag of claim 10 , further comprising a cord configured to constrict and/or expand an aperture at least partially defined by the hood.

12. The multi-climate sleeping bag of claim 9 , wherein the insulating material of the bottom panel comprises one or more of a down material, an offset quilted material, a shingled synthetic material, or a combination thereof.

13. The multi-climate sleeping bag of claim 9 , wherein the first top panel comprises an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell, the insulating material of the first top panel comprises a down material, an offset quilted material, a shingled synthetic material, or a combination thereof.

14. The multi-climate sleeping bag of claim 9 , wherein the insulating material of the second top panel comprises a down material, an offset quilted material, a shingled synthetic material, or a combination thereof.

15. The multi-climate sleeping bag of claim 9 , further comprising a draft tube disposed adjacent the at least a portion of the second fastener mechanism.

16. The multi-climate sleeping bag of claim 9 , wherein the second climate zone has a limit rating for a lower temperature than a limit rating of the first climate zone.

17. The multi-climate sleeping bag of claim 9 , wherein the third climate zone has a limit rating for a lower temperature than a limit rating of one or more of the first climate zone and the second climate zone.
