Aerobie throwing ring (Ø 25cm); enormous flight distances, precise flight, and a high-quality, technical design have made Aerobie rings so popular. Thanks to their low mass, "Aerobie" throwing rings are exceptionally stable in the air. Their inventor, Alan Adler, incorporated findings from his research and teaching at Stanford University, Princeton University, and NASA into their development, focusing on precision, stability, and aerodynamics. Even when thrown with minimal effort, "Aerobie" rings travel great distances due to their minimal air resistance and land with pinpoint accuracy. Rounded, soft edges make them easy to catch. The Aerobie product range offers frisbees and throwing rings in various sizes and with diverse features.
