District Vision Nagata Speed Blade Grey D+ Black Rose

The Nagata Speed Blade for runners is an ultra-lightweight nylon and titanium frame construction. Our D+ lens is handcut and polished in Japan for unrivaled visibility in various performance conditions.

Made in Japan

Our performance eyewear system was developed over a two year technical testing period, involving New York City athletes and Japanese engineering. The frame features D+ lens technology, an adjustable hypoallergenic rubber nose pad and temple tips with a titanium core.

The Most Comfortable Sports Frame

The hypoallergenic 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 fitting. Your sunglasses are accompanied by our highest grade 630GSM microfibre running pouch and ships in a Munken print 150g paper box.

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.

A Transitionary Lens Technology

D+ Black Rose is an advanced sports lens engineered for trail running and physical pursuits that involve changing light conditions. The lens has a variable light transmission allowing 15.6% to 35.15% of light through. This enhances visibility in a variety of performance conditions.

The 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.
