District Vision holds nothing back when it comes to attention to detail and intentional design. The Nagata Speed Blade is a result of extensive R&D and features their D+ transition lens, which allows 15.6%-35.5% of light through depending on conditions. They were designed with trail running in mind, but are perfect for any outdoor pursuit or as a clean, lightweight daily driver.
