Abstract: A reversible backpack includes a backpack shell with first and second surfaces. The backpack shell is reversible through an access opening thereinto, such that either of the first and second surfaces is selectable as the exterior of the bag. One or more carrying straps are releasably connected proximate to the top of the backpack shell and, during reversal, are passed through strap openings proximate to the bottom of the backpack shell. A pocket shell located in a pocket opening of the backpack shell defines a pocket volume separated from the interior volume of the backpack shell. Pocket access openings in first and second faces of the pocket shell allow access into the pocket regardless of which backpack shell surface is exterior.
