A backpack includes a body having a closure portion which defines an opening through which an interior region of the body can be accessed selectively. In the opened position, end portions of the closure portion are extended away from one another, permitting access to the interior region. In the closed position, end portions are moved toward one another, inhibiting access to the interior region. A cord coupled to the strap assembly and to the end portions of the closure portion has a first configuration which permits movement of the closure portion to the open position, and a second configuration which inhibits extension of the end portions of the closure portion away from one another. A method for securing a backpack in a closed position includes positioning the cord in the second configuration, which permits drawing of the closure portion to a closed position.

1. A backpack comprising: a strap assembly for mounting the backpack to a user, the strap assembly comprising an anchor portion having cord-support surfaces;a body coupled to the strap assembly, the body having a closure portion defining an opening through which an interior region of the body can be accessed selectively, the closure portion having an opened position with end portions extended away from one another thus permitting access to the interior region of the body through the opening, and the closure portion having a closed position with end portions moved toward one another thus inhibiting access to the interior region of the body through the opening; anda cord coupled to the strap assembly and to the end portions of the closure portion of the body, the cord having a first configuration permitting extension of the end portions of the closure portion away from one another and movement of the closure portion to the opened position, the cord also having a second configuration inhibiting extension of the end portions of the closure portion away from one another and maintaining the closure portion in the closed position,wherein the cord is positioned to slide with respect to two pairs of the cord-support surfaces, each pair of the cord-support surfaces being movable with respect to one another from relatively near positions to relatively far positions as the closure portion is moved from the opened position to the closed position,wherein each pair of cord-support surfaces comprises an upper cord-support surface and a lower cord-support surface,wherein the upper cord-support surfaces and lower cord-support surfaces are movable with respect to one another from relatively near positions to relatively far positions as the closure portion is moved from the opened position to the closed position. 2. The backpack of claim 1, the end portions of the closure portion each having a cord-support surface, wherein the cord is positioned to slide with respect to the cord-support surfaces of the closure portion, each cord-support surface of the closure portion being movable with respect to one another from relatively far positions to relatively near positions as the closure portion is moved from the opened position to the closed position. 3. The backpack of claim 2, wherein the cord is coupled to at least one lower anchor. 4. The backpack of claim 3, wherein the cord is disposed through or engaged by at least one upper anchor. 5. The backpack of claim 4, wherein the cord extends from a first lower anchor to a first lower cord-support surface of the anchor portion, from the first lower cord-support surface of the anchor portion to a first cord-support surface at an end portion of the closure portion, from the first cord-support surface of the end portion of the closure portion to a first upper cord-support surface of the anchor portion, from the first upper cord-support surface of the anchor portion to the first lower anchor, from the first lower anchor to an upper anchor, and from the upper anchor directly or indirectly to a second lower anchor. 6. The backpack of claim 5, wherein the cord extends from the second lower anchor to a second lower cord-support surface of the anchor portion, from the second lower cord-support surface of the anchor portion to a second cord-support portion at an end portion of the closure portion, from the second cord-support surface at an end portion of the closure portion to a second upper cord-support portion of the anchor portion, and from the second upper cord-support portion of the anchor portion to the second lower anchor. 7. The backpack of claim 6, wherein the first and second (i) anchors, (ii) lower cord-support surfaces of the anchor portion, (iii) cord-support surfaces of the closure portion, and (iv) upper cord-support surfaces of the anchor portion are mirror images of each other. 8. The backpack of claim 7, wherein the portions of cord extending from the first lower anchor to the lower cord-support surface of the anchor portion and from the second lower anchor to the second lower cord-support surface of the anchor portion loop around each other. 9. A backpack comprising: a strap assembly for mounting the backpack to a user, the strap assembly comprising an anchor portion having cord-support surfaces;a body coupled to the strap assembly, the body having a closure portion defining an opening through which an interior region of the body can be accessed selectively, the closure portion having an opened position with end portions extended away from one another thus permitting access to the interior region of the body through the opening, and the closure portion having a closed position with end portions moved toward one another thus inhibiting access to the interior region of the body through the opening; anda cord coupled to the strap assembly and to the end portions of the closure portion of the body, the cord having a first configuration permitting extension of the end portions of the closure portion away from one another and movement of the closure portion to the opened position, the cord also having a second configuration inhibiting extension of the end portions of the closure portion away from one another and maintaining the closure portion in the closed position,wherein the cord is positioned to slide with respect to two pairs of the cord-support surfaces, each pair of the cord-support surfaces being movable with respect to one another from relatively near positions to relatively far positions as the closure portion is moved from the opened position to the closed position,wherein each pair of cord-support surfaces comprises an upper cord-support surface and a lower cord-support surface,wherein the cord-support surfaces are arranged at apices of a four-sided geometry,wherein the upper cord-support surfaces and lower cord-support surfaces at the apices of the four-sided geometry are movable with respect to one another from relatively near positions to relatively far positions as the closure portion is moved from the opened position to the closed position.
