Backpacks with cooperatively adjusted hip belts and compression straps
Backpacks with cooperatively adjusted hip belt segments and compression strap segments. A backpack includes a pack body, a shoulder strap, and a belt assembly. The pack body includes a back panel and an exterior panel. The belt assembly includes a compression strap segment, a hip belt segment, an adjustment strap, and a releasable fastener. The backpack includes a belt assembly waist loop with a belt assembly waist perimeter. Each adjustment strap is configured to selectively adjust each of the pack volume and the belt assembly waist perimeter. The belt assembly is configured such that, responsive to the user applying a tension force to the adjustment strap, each of a pack volume and the belt assembly waist perimeter decreases by a respective degree that depends upon a ratio of the force required to decrease the pack volume to the force required to decrease the belt assembly waist perimeter.

the movement of the compression strap segment adjustment end by the first distance corresponds to a compression of a volume of the storage compartment, and
the movement of the hip belt segment adjustment end by the second distance corresponds to decreasing the perimeter of the belt assembly around the user's waist.
8. The backpack of claim 1 , wherein the at least one adjustment strap is configured to compress a volume of the storage compartment in response to the force applied by the user to the at least one free end if the force required to compress the volume of the storage compartment exceeds the force required to decrease the perimeter of the belt assembly around the user's waist.
9. The backpack of claim 1 , wherein,
the compression strap segment pack end is coupled to the pack body such that the at least one compression strap segment is configured to apply a compression force to adjust a volume of the storage compartment, and
the at least one hip belt segment is configured to support the backpack on the user's hips.
10. The backpack of claim 1 , wherein the storage compartment is configured to carry one or more of food, water, clothing, camping equipment, or sporting equipment.
11. The backpack of claim 1 , wherein,
the storage compartment comprises a hydration bladder compartment configured to hold a hydration system, and
the pack body comprises at least one hydration tube passage, the at least one hydration tube passage is configured to permit fluid flow out of the hydration bladder compartment.
12. The backpack of claim 1 , wherein the pack body further comprises:
a back panel configured to be adjacent to the user's back when the user wears the backpack;
an exterior panel facing away from the back panel and separated from the back panel by the storage compartment; and
at least one side panel positioned between the back panel and the exterior panel,
wherein the back panel, the exterior panel and the at least one side panel are formed either of a single component or distinct components.
13. The backpack of claim 1 , wherein the pack body further comprises at least one inner side pocket, the at least one inner side pocket is positioned between the compression strap segment and the pack body.
14. The backpack of claim 1 , wherein the at least one adjustment strap is configured to:
adjust the belt assembly around the user's waist in response to the force applied by the user to the at least one free end, and
compress the pack body via the compression strap segment in response to the force applied by the user to the at least one free end.
15. The backpack of claim 1 , wherein,
the at least one adjustment strap is slidingly coupled to a fastener such that the fastener is positioned between the at least one compression strap segment and the at least one hip belt segment, and
the fastener is releasable and configured to translate along a length of the at least one adjustment strap.
16. The backpack of claim 1 , wherein,
the at least one compression strap segment comprises a left compression strap segment and a right compression strap segment,
the at least one hip belt segment comprises a left hip belt segment and a right hip belt segment,
the at least one adjustment strap comprises a left adjustment strap and a right adjustment strap, wherein,
the left compression strap segment is coupled to the left hip belt segment via the left adjustment strap, and
the right compression strap segment is coupled to the right hip belt segment via the right adjustment strap.
