The Horizon Blade is a performance eyewear frame developed in collaboration with climber Ashima Shiraishi, refined through two years of iterative testing for outdoor climbing use. Built on a 6-base frame with extended peripheral coverage, the design features four ventilation holes to reduce fogging during high-output activity, while 125mm temples are sized to work with helmets for climbing and cycling. The D+ Black Rose lens transmits 15.67% of visible light, making it suited to variable light conditions on trail and rock, and delivers 100% UVA/UVB protection via a shatterproof polycarbonate construction with anti-reflective and oleophobic interior coatings. Adjustable nose pads and grade 2 titanium-core temple tips provide a secure, customizable fit.
