Kazu Tourer Green Tortoise
D+ Earth Vision


Made in Japan.

Inspired by the 1960's and 1970's alpine style movement in mountaineering, the Kazu Tourer is the result of a collaboration between Tracksmith and District Vision, two projects with strong foundations in running.

In the 60’s and 70’s, ‘alpine style’ was an intentional departure from the ‘siege tactics’ of many well-known mountaineering ascents, where climbing parties had relied on small armies of porters, cached gear and supplies, fixed ropes, and tremendous governmental support to complete ascents in the name of nationalistic glory. Alpine style, on the other hand, emphasized self-sufficiency, efficiency of movement in technical terrain, and the ability to exist in solitude in the mountain environment with everything a climber needed in his or her rucksack, allowing an existence free of the trappings and dependencies of traditional ascents.

The Kazu Tourer features strategically ventilated lenses, an inlaid titanium bridge badge, and integrated side shields to mitigate ambient light and glare, assisting the wearer in focusing on the terrain ahead, free of distraction. The frames feature a luxurious glossy finish and District Vision’s signature D+ therapeutic grade lenses, constructed from a proprietary form of shatterproof polycarbonate. The lens interiors are treated with both anti-reflective and oleophobic coatings for holistic eye protection and water and oil repellency. The frames feature beta-titanium armature and hardware with fully adjustable and hypoallergenic rubber nose pad and temple tips to provide a secure and customizable fit.


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.

Developed especially for this collaboration, D+ Earth Vision is a polarized lens that mitigates reflected light and allows 10.03% of visible light transmission, 6.06% of blue light transmission, and blocks 100% of UVA/UVB rays. The tortoise pattern is applied by hand at our factory in Japan, meaning that no two frames are identical.
