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;
• and
• a rail system secured to the side walls and to the upper rim, comprising one or more rails, including four internal rails and four external rails, with one internal rail extending along an interior of each of the four side walls, and/or one external rail extending along an exterior of each of the four side walls, wherein the four internal rails are not continuous with each other, and the four external rails are not continuous with each other.
