Takeyoshi Altitude Master Silver D+ Onyx Mirror

The Takeyoshi Altitude Master is an 8 base frame construction designed for rigorous outdoor pursuits. The ergonomic form is engineered to aid ventilation and enhance the field of vision whilst protecting the eyes. The frame features temples architected for helmet use, D+ lens technology, an adjustable hypoallergenic rubber nose pad and temple tips with a titanium core.

The Most Comfortable Sports Frame

Our hypoallergenic adjustable nosepad is mounted with titanium screws and a titanium core to produce the lightest, most comfortable sports frame. We recommend visiting a preferred optician to ensure a durable and comfortable fit.

Each frame is accompanied with an Ultrasuede® pouch, serving as both a storage solution and a lens-cleaning accessory. Ultrasuede® is a soft material with a luxurious texture incorporating 30% recycled plant-based fibers, utilizing advanced fiber technology pioneered by Japan’s Toray Industries, Inc.

Research & Development

District Vision researches and develops tools for outdoor pursuits. We have collaborated with athletes to produce the world's first proprietary Japanese eyewear system. With all our products, we maintain the methodology of Kaizen, the concept of continuous improvement, to make the finest tools for athletes.

Titanium Grade 2 Core

Our frames are crafted with a titanium grade 2 core, providing strength while retaining flexibility. Grade 2 ensures durability along with a high level of corrosion resistance, making it a material widely utilized in aerospace applications.

D+ Onyx Mirror

D+ Onyx Mirror was developed for physical pursuits requiring maximum sun protection. The mirror coating facilitates additional infrared screening. The lens offers 100% UVA/B protection while transmitting 16.19% of visible light and 15.99% of blue light. Athletes often forget sunglasses are a medical device. Unlike our skin, our eyes do not contain melanin. This means each time we expose them to sunlight they become more sensitive.

Sports Lens of the Future

D+ lens technology is constructed from a proprietary form of polycarbonate, which is shatterproof. The lens interior features an anti-reflective application for holistic eye protection. The lens is finished with our oleophobic treatment making it water and oil repellent.
