Clamshell backpack with accessory attachment means

A backpack comprising:

• a housing, the housing having a height, width, depth, and central axis with corresponding imaginary central plane, the central plane running parallel with the height and depth and orthogonally to the width, the housing further having an exterior and interior and comprising:
• (a.) a top region and an opposing bottom wall, the bottom wall being generally rectangular and having length and width edges meeting at four generally rounded corners;
• (b.) a front wall and an opposing back pad;
• (c.) a sidewall extending between the front wall and back pad and running through a portion of the top region while intersecting the central plane, the sidewall terminating at front and back edges corresponding with the front wall and back pad, respectively, the sidewall further terminating at the width edges of the bottom wall, such that the sidewall, bottom wall, and front wall generally meet at two front corners out of said four, while the sidewall, bottom wall, and back pad generally meet at two back corners out of said four;
• (d.) a zippered primary enclosure with sliders, the primary sliders following an angled primary pathway along the housing to provide a primary open or primary closed configuration, the primary enclosure associated with a primary compartment having interior surfaces and accessible via the primary open configuration, the primary pathway substantially coinciding with said back edge and crossing the two back corners to further run along the bottom wall toward its length edge that is bounded by the two front corners, such that the zipper runs along a substantial portion of the bottom wall's width dimension in two mirrored paths relative to the central plane, each path having a terminal edge near a front corner, the sliders continuously zippable along the primary pathway from terminal edge to terminal edge;
• (e.) a plurality of attachment interfaces for anchoring accessories and storage cases to the backpack, each interface comprising a plurality of consecutively arranged loops attached via bartack stitching, such that the loops and stitched portions are linearly arranged in an alternating fashion;
• (f.) a pair of shoulder straps attached to the back pad near the top region, the shoulder straps generally being symmetrically disposed relative to the central plane, each shoulder strap having an outer and inner surface;
• and,
• wherein two attachment interfaces are positioned on the sidewall's exterior and opposing each other relative to the central plane, wherein each shoulder strap includes an attachment interface, and wherein the primary compartment includes an attachment interface positioned on at least one interior surface.
