Introducing our collaboration with California-based performance eyewear and running brand District Vision. Built for extreme environments, this collaborative AW25 capsule line includes both proprietary lens technology and advanced thermoregulatory fabrics. The result: an Arctic‑grade exploration kit built to withstand whatever nature throws its way, without compromising on appearance. The capsule reflects District Vision’s ethos of mindful living fused with high-performance sportswear, while upholding 66°North’s nearly 100-year legacy of functional durability.

Developed to commemorate District Vision’s 10th anniversary in 2025, the Eiichi Explorer Ti builds upon the design principles established with the 2015 Keiichi Standard, the brand’s inaugural eyewear model. Named in honor of the late Mr. Eiichi Nakanishi and the Japanese craftsmen he led for over 50 years, the frame is engineered with a 6-base lens curvature and aerospace-grade titanium temples measuring 130mm for exceptional strength and lightweight durability.

Designed for 66°North and made in Japan, the frame features TR90 nylon glare hoods contoured for alpine performance, offering protection against intense sun, wind, rain, and snow in the world’s most extreme climates. To ensure a secure and comfortable fit across a wide range of facial structures, it includes an enlarged, adjustable hypoallergenic nose pad, while shatterproof lenses with advanced oleophobic and anti-reflective coatings preserve optical clarity.
