The real story here is in the materials. Algae Foam is a high-performance flexible foam made from algae biomass harvested from freshwater sources throughout the world. Harvesting the algal blooms that make up Algae Foam results in cleaner water and air. You'll not only be ripping, but making the world a safer place.
