These grey and red District Vision Keiichi Calm Tech sunglasses have been made with Japanese engineering and feature a porous structure which absorbs moisture. Complete with hypoallergenic nose pads, this pair boasts a light titanium frame, tinted lenses and in-built shatterproof and anti-reflective D+ lens technology. Arriving in a microfiber pouch and presentation box, we can see things in a different light now thanks to District Vision.
