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.

The Keiichi performance eyewear system was developed over a two year technical testing period, involving athletes and Japanese engineering. The frame features D+ lens technology, rubber/titanium nose pad and temple tips. D+ Brown Gradient is a polycarbonate 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.
