  • Patent number: 6216926
    Abstract: A combination workout backpack and detachable backpack bag is disclosed in which the workout backpack and one or more standard weighted weight bags are used for training, i.e., building strength and endurance, for hiking.

The workout backpack includes two vertically-extending, side-by-side, weight storage compartments which are conformable to one or more weight bags to inhibit horizontal and vertical movement of the standard weighted weight bags when training. A plurality of straps with releasable interlocking buckle clasps releasably attach a vertically-extending central portion, opposite lateral side portions, and a top portion of the workout backpack and to the detachable backpack bag to form an integral unit similar to a conventional backpack.
