Carry your stuff with cardboard.
The description inside the Bucky Bag reads:
The Bucky Bag is a geodesic game-changer. Tetrahedronally engineered to dymaxion-out all of your life engineering issues, the Bucky is one sleek piece of paper re-purposing. Part of a continuum in the rich typology of geodesic integration, this satchel will be a new page in your life liberated from constraints and tutelage. The Bucky is designed with “Tensegrity”, a philosophical model of coherence and an anticlassical approach to structure, construction and load-bearing. You cannot fold in the face of pressure. In the immortal words of the man himself: “Don’t fight forces, use them.”
