The Nagata Speed Blade is a running-specific sunglass built on an ultra-lightweight nylon frame reinforced with a grade 2 titanium core in the temple tips for durability without added bulk. Adjustable nose pads and flexible temple tips deliver a secure, personalized fit suited to high-movement activity. The D+ Sports Yellow lens is crafted from shatterproof polycarbonate with 74.40% visible light transmission and 31.67% blue light transmission, making it engineered for low-light conditions such as dawn and dusk runs. Interior anti-reflective and oleophobic coatings reduce glare and repel water and oil for clear, unobstructed vision.
