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.
1. A backpack comprising:
a main body comprising a front exterior surface and a rear exterior surface disposed opposite the front exterior surface, the main body further comprising one or more interior surfaces 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 the front exterior surface of the main body;
a first cinching cord coupled to the first shoulder strap and the second shoulder strap, wherein the coupling between the first cinching cord and one or more of the first shoulder strap and the second shoulder strap comprises an adjustable coupling, and wherein at least a portion of the first cinching cord is disposed adjacent a top end of the front exterior surface of the main body; and
a second cinching cord coupled to the main body and extending through at least a portion of the cinching layer, wherein at least a portion of the second cinching cord is disposed adjacent a top end of the cinching layer and is 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.
2. The backpack of claim 1 , further comprising a first hip member extending through at least one first main body ring coupled to the main body and at least one first shoulder strap ring coupled to the first shoulder strap, the first hip member adjustably coupled to a first anchor coupled to the main body.
3. The backpack of claim 2 , further comprising a second hip member extending through at least one second main body ring coupled to the main body and at least one second shoulder strap ring coupled to the second shoulder strap, the second hip member adjustably coupled to a second anchor coupled to the main body.
4. The backpack of claim 3 , wherein the second hip member is configured to be releasably coupled with the first hip member to define an adjustable hip belt, and wherein adjustment of a tension in the hip belt causes adjustment of a cinching force between the first and second shoulder strap and the main body.
5. The backpack of claim 1 , further comprising a first aperture formed in the main body and configured to allow access to the first compartment.
6. The backpack of claim 5 , further comprising a first fastening mechanism configured to selectively open or close at least a portion of the first aperture.
7. The backpack of claim 1 , further comprising a second aperture formed in the main body and configured to allow access to a second compartment disposed in or defined by the main body.
8. The backpack of claim 7 , further comprising a second fastening mechanism configured to selectively open or close at least a portion of the second aperture.
9. The backpack of claim 1 , wherein the main body comprises a support panel.
10. The backpack of claim 9 , wherein the support panel comprises a foam support member at least partially enclosed in a material.
11. The backpack of claim 10 , wherein the foam support member has a curvilinear shape configured to abut a back of a wearer.
12. The backpack of claim 1 , further comprising a first chest member coupled to the first shoulder strap and a second chest member coupled to the second shoulder strap, wherein the first chest member is configured to be releasably coupled to the second chest member across a torso of a wearer.
13. The backpack of claim 1 , wherein the adjustable coupling between the first cinching cord and one or more of the first shoulder strap and the second shoulder strap is effectuated using a cord lock.
14. The backpack of claim 1 , wherein the adjustable coupling between the first cinching cord and one or more of the first shoulder strap and the second shoulder strap is configured to allow a portion of the first cinching cord to be engaged by a wearer of the backpack to adjust a tension force applied to the first cinching cord.
15. The backpack of claim 1 , wherein the adjustable coupling between the first cinching cord and one or more of the first shoulder strap and the second shoulder strap is configured to allow an end of the first cinching cord to be engaged by a wearer of the backpack to adjust a tension force applied to the first cinching cord.
