Portable collapsible modular and waterproof storage and transportation system

A storage container comprising:

• an exterior including four side walls and a bottom, the four side walls collapsible to allow the storage container to take up less space when not in use;
• a bi-stable support mechanism coupled to one or more of the four side walls, reconfigurable between at least a first stable configuration and a second stable configuration while coupled to the one or more of the four side walls, wherein the bi-stable support mechanism holds the storage container at a larger size when in the first stable configuration, and allows the container to collapse to a smaller size when in the second stable configuration;
• an upper rim secured to an upper portion of the side walls and having a rigid structure for supporting a shape of the storage container, wherein the rim includes two central hinges on opposite portions of the rim, the two central hinges configured to allow the rim to close on itself to seal the storage container in a watertight manner;
• and
• a rail system secured to the side walls and to the upper rim, comprising one or more rails extending along an interior and/or an exterior of the side walls.
