The Arbor Mystic's exclusive design amplifies return and maximizes durability. Expect fatter ollies, spring-loaded initiation, and reduced swing weight. The Mystic drives through transitions, releasing cleanly into any pipe trick, with a geometry that opens the door to those afternoon all-mountain expression sessions. EcoTechnology Bamboo Reinforced Core. Bamboo is one of the most renewable, eco-friendly, and resilient materials known to man. It has a higher tensile strength than steel; yet it's light, flexible, and resistant to compression. Bamboo increases board power and durability - creating 60% more return than standard materials, with an effective life 40 times longer than that of carbon fiber.
