(48) The flap 10, may comprises an exterior surface 16, a connection end 18, a buckle end 20, a first upper buckle strap 22, and a second upper buckle strap 24. The connection end 18 of the flap 10 is connected to the back panel 26 at least 6 inches away from the top end 28 of the back panel 26 to enclose the items contained in the backpack and to prevent the deformation of the rectangular opening created by the top end 78 of the front panel 12, the top end 28 of the back panel 26, the first side panel 32, and the second side panel 14. Preventing the deformation of the rectangular or square shape enables quad chairs to more easily be inserted into the backpack. If the opening of the backpack was easily deformed, the edges of the opening would easily catch on the legs or other components of the quad chair. By placing the flap 10 further away from the opening, the weight of the flap 10 is distributed among the back panel 26 and not focused on the top end 28 of the back panel 26 creating the opening. The flap 10 comprises a first upper buckle strap 22 and a second upper buckle strap 24 attached by stitching or adhesive to the buckle end of the flap 10. The buckle straps allow the flap 10 to be detachably connected to another part of the backpack to ensure the flap 10 stays closed. However, other alternatives are contemplated. For example, flap 10 can have a zippered pocket 34 on the exterior surface of the flap 10 for quick access to small items.

(49) The first strap 64, comprises a first end 76 and a second end 79. The first end 76 of the first strap 64 is connected by stitching or adhesive to the back panel 26 near the point of attachment for the flap 10 on the back panel 26. The second end 79 of the first strap 64 is connected by stitching or adhesive to the back panel 26 in a position closer to the bottom end of the back panel 26. The two points of connection create a loop, enabling a user to place their arm through the first strap 64 so the backpack may rest on the shoulder of the user. However, other alternatives are contemplated. For example, the first strap 64 may have padded surfaces or pockets attached.

(50) The second strap 65, comprises a first end 77 and a second end 80. The first end 77 of the second strap 65 is connected by stitching or adhesive to the back panel 26 near the point of attachment for the flap 10 on the back panel 26. The second end 80 of the second strap 65 is connected by stitching or adhesive to the back panel 26 in a position closer to the bottom end of the back panel 26. The two points of connection create a loop, enabling a user to place their arm through the second strap 65 so the backpack may rest on the shoulder of the user. However, other alternatives are contemplated. For example, the second strap 65 may have padded surfaces or pockets attached.

(51) The reinforcement strap 66, is connected by stitching or adhesive to the back panel 26, the flap 10, the first strap 64, the second strap 65, and the loop 86. The reinforcement strap 66 connects to the back panel 26 in a manner so that the flap 10, the first strap 64, the second strap 65, and the loop 86 are positioned between the reinforcement strap 66 and the back panel 26. The reinforcement strap 66 serves to distribute force placed on the first strap 64, the second strap 65, the flap 10, and the loop 86. By distributing the force, the connection points for the first strap 64, the second strap 65, the flap 10, and the loop 86 will experience less wear and are less likely to fail or tear off of the back panel 26.

(52) The reinforced bottom 38, is attached to the bottom end 46 of the front panel 12, the bottom end 74 of the back panel 26, the first side panel 32, and the second side panel 14. The reinforced bottom 38 prevents items inside the backpack enclosure from falling out. In some embodiments the reinforced bottom 38 may be made of more layers, thicker material, or have added stitching to enable a stronger and more durable area of the embodiment because it will receive the bulk of the force from any items contained within the backpack.
