Abstract
A backpack which includes a main bag, suspension system, frame, and additional miscellaneous parts. It combines the superior comfort of external frame backpacks, with the elegant style of internal frame backpacks. The frame is strapped within the main bag to create a semi-rigid surface against the back. The suspension system's shoulder harness is removable, and adjustably connected through the semi-rigid surface by screws. The shoulder harness is vertically adjustable and swivels to accommodate different shoulder widths. The suspension system's waist harness is removable, and rigidly connected through the semi-rigid surface by screws. The waist harness provides optimum weight transfer onto the hips and creates an air gap, providing ventilation to the back. By removing the frame and placing a cover on it, a seat is formed. By aligning the seat linearly with additional feet, and inserting elongated rails between them, a frame for a cot is formed.
