District Vision Takeyoshi Altitude Master — Eight-Base Precision. Made in Japan.

The District Vision Takeyoshi Altitude Master is an eight-base frame construction built for rigorous outdoor pursuits where eye protection and optical clarity are non-negotiable. Engineered in Japan with an ergonomic form that aids ventilation, enhances field of vision and wraps the eye for comprehensive protection, it handles everything from high-altitude mountain days to fast road efforts without compromise. Helmet-compatible temples, adjustable nose pads and a grade 2 titanium core deliver a fit that stays secure however hard the pursuit gets.

 

 

D+ Therapeutic-Grade Lenses

The signature D+ lenses are crafted from shatterproof polycarbonate with anti-reflective and oleophobic coatings on the interior surfaces — repelling water and oil whilst providing comprehensive protection across all conditions. The D+ Copper lens mitigates reflected light for enhanced contrast and visual clarity, transmitting 10.03% of visible light and 6.06% of blue light whilst blocking 100% of UVA/UVB rays. A lens developed for the kind of conditions that demand the most from eyewear.

 

 

Engineered for the Outdoors

The eight-base wrap construction provides greater peripheral coverage and eye protection than standard sports frames, whilst the ergonomic form maintains airflow to prevent fogging during sustained efforts. Adjustable nose pads and temple tips allow precise, personalised fit customisation, reinforced by a grade 2 titanium core in the temple tips for added structural durability. Helmet-compatible temples make the Altitude Master as capable on a bike or in the mountains as it is on the road.
