SunGod Forty2s Iris Running Sunglasses

Engineered to run. From 5k to 42k and beyond, go the distance in FORTY2s.

Crafted with an 8KO Iris Photochromic lens, the SunGod Forty2s provide you with clear vision no matter the time of day or weather. Expertly, the lens reacts to changing light, responding by lightening or darkening for better protection, with the lens darkening as the day brightens. Blocking 100% of both UVA and UVB rays, the Ultras Air meet the UV400 standard with ease. Covering the lens is a triple layer of scratch resistance, ensuring the sunglasses last the test of time, but if a lens change is something you need or want, easily change the lenses out for a different pair as you like. Ensuring a distraction-less run, the Forty2s have a run specific design, with TPU Pads located on the arms of the sunglasses, causing moisture-gripping stick for zero-bounce wear. A built in airflow system has been added, reducing heat behind the lenses and preventing unwanted fogging. Interchangeable nose pads have been included with the sunglasses of different sizes to ensure you can achieve the most comfortable fit possible. The Forty2s sunglasses have PopLock Screwless hinges, meaning the glasses are less likely to snap if put under pressure, allowing a flex without breaking. Finally, a pouch is included so you can tuck the sunglasses away safely when not in use; the pouch also works as a cloth to rub away smudges and dirt.
