ABSTRACT:
A modular backpack for carrying heavy loads over substantial periods of time includes a back panel with a polyfoam layer, a stretch fabric cover, and a fabric layer between the polyfoam layer and the back panel, all thermally molded to the back panel to define a number of smaller polyfoam pads, a carry bag attached to the back panel, a separate waist support having separate molded left and right waistband pads fastened thereto, a molded bun pad of multilayered polyfoam positioned between the waistband pads and stitched to the lower part of the back panel and to a bottom panel of the carry bag, leaving a space between itself and the back panel to insert and remove the waist support and waistband pads. A pair of generally triangular stress panels are stitched to the lower part of the back panel on each side so as to overlay the outside of the waistband pads and padded shoulder straps are attached to the stress panels and to the upper part of the back panel.
