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 backpack of claim 1, wherein the at least one shoulder strap includes a pair of shoulder straps; wherein the at least one compression strap segment includes a pair of compression strap segments; wherein the at least one hip belt segment includes a pair of hip belt segments; wherein the at least one adjustment strap includes a pair of adjustment straps; and wherein the belt assembly waist loop is defined by each hip belt segment, the releasable fastener, a portion of each adjustment strap that extends between the corresponding hip belt segment and the releasable fastener, and a portion of the pack body that extends between the respective hip belt segment pack ends of the pair of hip belt segments. 3. The backpack of claim 2, wherein each adjustment strap includes: a loop portion that extends between the compression strap segment adjustment end of the corresponding compression strap segment and the hip belt segment adjustment end of the corresponding hip belt segment; anda free end extending from the loop portion at one of the compression strap segment adjustment end of the corresponding compression strap segment and the hip belt segment adjustment end of the corresponding hip belt segment;wherein the backpack includes a pair of belt assembly internal loops, each belt assembly internal loop having a corresponding belt assembly internal loop perimeter, wherein each belt assembly internal loop is at least partially defined by:a corresponding compression strap segment of the pair of compression strap segments;a corresponding hip belt segment of the pair of hip belt segments;the loop portion of a corresponding adjustment strap of the pair of adjustment straps; anda portion of the pack body that extends between the compression strap segment pack end of the corresponding compression strap segment and the hip belt segment pack end of the corresponding hip belt segment;wherein the free end is configured to be pulled by the user to selectively decrease the corresponding belt assembly internal loop perimeter. 4. The backpack of claim 3, wherein the free end of a corresponding adjustment strap of the pair of adjustment straps is configured to be pulled by the user to increase a length of the free end of the corresponding adjustment strap and to decrease a length of the loop portion of the corresponding adjustment strap. 5. The backpack of claim 3, wherein each adjustment strap is configured to adjust the belt assembly internal loop perimeter of the corresponding belt assembly internal loop to selectively adjust at least one of the pack volume and the belt assembly waist perimeter when the user wears the backpack. 6. The backpack of claim 3, wherein the belt assembly is configured such that, responsive to the user pulling the free end of a corresponding adjustment strap of the pair of adjustment straps when the user wears the backpack, at least one of: (i) the belt assembly waist perimeter is decreased; and(ii) the belt assembly internal loop perimeter is decreased. 7. The backpack of claim 6, wherein, responsive to the user pulling the free end of the corresponding adjustment strap when the user wears the backpack: (i) the belt assembly waist perimeter is decreased by a greater extent than the belt assembly internal loop perimeter is decreased if pulling the corresponding hip belt segment adjustment end toward the releasable fastener requires less force than pulling the corresponding compression strap segment adjustment end toward the releasable fastener, and(ii) the belt assembly internal loop perimeter is decreased by a greater extent than the belt assembly waist perimeter is decreased if pulling the corresponding hip belt segment adjustment end toward the releasable fastener requires more force than pulling the corresponding compression strap segment adjustment end toward the releasable fastener. 8. The backpack of claim 7, wherein, responsive to the user pulling the free end of the corresponding adjustment strap when the user wears the backpack, a ratio of an extent to which the belt assembly waist perimeter is decreased to an extent to which the belt assembly internal loop perimeter is decreased is proportional to a ratio of the force required to pull the corresponding hip belt segment adjustment end toward the releasable fastener to the force required to pull the corresponding compression strap segment adjustment end toward the releasable fastener. 9. The backpack of claim 3, wherein, responsive to the user exerting a tension force on the free end of a corresponding adjustment strap of the pair of adjustment straps, at least one of the compression strap segment adjustment end of the corresponding compression strap segment and the hip belt segment adjustment end of the corresponding hip belt segment is urged toward the releasable fastener with a force that is greater than the tension force exerted on the free end by the user. 10. The backpack of claim 1, wherein the releasable fastener is slidingly coupled to each adjustment strap such that the releasable fastener is selectively positioned along the adjustment strap between the compression strap segment adjustment end of a corresponding compression strap segment and the hip belt segment adjustment end of a corresponding hip belt segment and such that the releasable fastener may translate along a length of the adjustment strap. 11. The backpack of claim 1, wherein the pack body has a pack body height, wherein each compression strap segment pack end is coupled to the pack body at a compression strap segment attachment region, and wherein the compression strap segment attachment region has a compression strap segment attachment region height that is at least 20% of the pack body height. 12. The backpack of claim 11, wherein the exterior panel includes the compression strap segment attachment region. 13. The backpack of claim 1, wherein each adjustment strap is non-adjustably coupled to the corresponding hip belt segment. 14. The backpack of claim 1, wherein each compression strap segment is configured to at least substantially overlap a corresponding hip belt segment of the at least one hip belt segment when the belt assembly extends around the user's waist. 15. The backpack of claim 1, wherein the at least one storage compartment includes a hydration bladder compartment configured to hold a hydration bladder. 16. The backpack of claim 15, wherein the backpack further includes at least one hydration tube passage configured to permit a drink tube of the hydration bladder to extend out of the hydration bladder compartment. 17. The backpack of claim 15 in combination with the hydration bladder. 18. The backpack of claim 1, wherein the backpack further includes at least one inner side pocket defined by a compression strap segment of the at least one compression strap segment, a side pocket panel that extends between the compression strap segment and a portion of the pack body proximal the back panel relative to the compression strap segment pack end of the compression strap segment, and a portion of the pack body that extends between the compression strap segment and the side pocket panel. 19. The backpack of claim 1, wherein the pack volume has a maximum total capacity that is at least 15 liters. 20. The backpack of claim 1, wherein the backpack further includes a compression strap segment storage compartment positioned in a compression strap segment of the at least one compression strap segment.
