Price reduction New and unused (Retail price ¥17,980) Compatible with Future Fins, honeycomb core, performance quad fins. The style is similar to Machado quads. ◎Honeycomb structure has high void content and is lighter than general resin foam or plastic. High strength and rigidity: The assembly of hexagonal cells provides superior compressive strength and durability compared to other materials of the same weight. The unique excellent flexibility of the honeycomb core makes it more flexible than fiberglass, achieving "medium flex" with excellent control and responsiveness. The honeycomb structure provides high shock absorption from multiple directions, and durability is improved as shocks are dispersed rather than concentrated. All-around performance: Lightweight and moderately flexible, making it a recommended fin that is easy to use in a wide range of wave conditions, from beach breaks to reef breaks. Experience the outstanding flexibility of the honeycomb core. ☆Features Speed performance Quad fins have less water resistance because there is no center fin, making it easy to achieve linear speed. They are particularly excellent at acceleration during "ups" (moving up and down the face of the wave). Good grip on the wave face The side fins grip the wave face firmly, allowing for stable riding even in thick waves or steep sections. ◎Please understand that the actual color may differ slightly from the image due to camera resolution.
