In collaboration with Spiber Inc., Planetary Equilibrium Tee which is made from Brewed Protein, materials are the protein fibers, films, and other types of materials manufactured using Spiber’s proprietary fermentation (brewing) process. The 82.5 to 17.5 plant-to-protein ratio recreates the current balance of the Earth’s biomass in a form that can be felt on the skin. In addition to symbolizing the proportion of plant to microbial life found on Earth, the shirt demonstrates the potential for an entirely animal-free manufacturing process.
