If you’re a runner – or, perhaps, just enamored by vintage prep design – you’re already a fan of Tracksmith. This brand leads the race in creating stylish running garments that don’t sacrifice on performance. Now, teaming up with District Vision, Tracksmith has come out with the Kazu Tourer. Inspired by alpine sporting, Italian racing, and crafted in Japan, the end result is a stylish frame that looks as good as it feels. Every inch of the real estate on these glasses is designed for comfort and performance. From the ventilated lenses to the side shields to minimize excess glare, these are shades with some serious tech behind them. Available in tortoise or glacier, either option will be a head-turning addition to your running wardrobe.
