HIGHEST QUALITY NEOPRENE
Our wetsuits are made with Japan’s most premium neoprene: Yamamoto #45, a limestone-based neoprene widely recognized as the best option for diving. Sourced from ultra-pure limestone in Mt. Kurohime, this material is engineered into a closed-cell foam filled with nitrogen micro-bubbles, creating exceptional insulation, lightness, and flexibility — exactly what divers need for warmth and effortless movement underwater. Unlike petroleum-based neoprene, Yamamoto #45 is more buoyant, warmer, and significantly more durable, maintaining its performance even after repeated compression at depth. Its long lifespan makes it a more sustainable choice, reducing the need for frequent replacements and minimizing environmental impact. By choosing the highest-grade neoprene available, we ensure every suit delivers superior comfort, thermal protection, and long-term reliability — truly the gold standard of premium, sustainable wetsuits.
