Takeyoshi Altitude Master

Story

Japanese-engineered mountain optics built for high-altitude clarity

District Vision designed the Takeyoshi Altitude Master to meet the extreme optical demands of alpine environments. Developed in Japan, these frames feature a reinforced titanium and stainless steel core that achieves a featherweight feel without sacrificing the rugged durability required for mountain summits. The D+ Water Gray lens is specifically tuned to provide neutral color perception and reduce eye fatigue during prolonged exposure to bright, high-altitude light.
