“The backpack is the development of a new way of assembly that utilizes the physical attributes of the materials from which it is made. It is constructed of a three-dimensional polygon system, which is the result of released tensions and convergence of the material.     While the backpack parts are in that state, the bag gets its exterior shape, and remains so due to geometric locks as a result of the shrink. The relationship between the parts enables the opening and closing of the backpack.”
