The District Vision Takeyoshi Altitude Master Sunglass is an eight-base performance frame engineered for demanding outdoor pursuits where protection, ventilation, and an expansive field of vision are essential. Made in Japan, the ergonomic wraparound silhouette features helmet-compatible temples, adjustable nose pads, and reinforced temple tips for a secure fit during high-output activity. Vented D+ Fire Mirror lenses use precision CNC-cut openings to promote airflow and reduce fogging, while the mirrored treatment provides additional infrared screening and complete UVA/B protection in bright conditions.
