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.

Abstract: A backpack may comprise a main body defining a first compartment, a first shoulder strap extending from the main body, a second shoulder strap extending from the main body, a cinching layer disposed adjacent an exterior surface of the main body, a first cinching cord coupled to the first shoulder strap and the second shoulder strap, and a second cinching cord coupled to the main body and extending through at least a portion of the cinching layer, wherein the second cinching cord is slideably coupled to the first cinching cord such that a tension applied to the first cinching cord causes the cinching layer to apply a compression force from the cinching layer toward the front exterior surface of the main body.
