Introducing the SunGod Forty2s Running Sunglasses, engineered for peak performance, comfort, and durability over long distances. Designed with elite runners in mind, the Forty2s are ultra-lightweight at just 27 grams and feature a zero-bounce, secure fit thanks to hydrophilic nose pads and TPU grip-touch ear socks that get grippier with sweat, ideal for intense marathons and trail runs. The frame is crafted from 100% recycled TR90, offering exceptional flexibility and strength while maintaining a sustainable footprint.

At the heart of the Forty2s are SunGods cutting-edge 8KO nylon lenses, which deliver up to 70% greater optical clarity than standard polycarbonate, combined with 100% UVA and UVB protection and a triple-layer scratch-resistant coating. Strategically designed vents reduce fogging and enhance airflow, ensuring uninterrupted vision in all weather conditions. Fully customisable with a modular design, runners can choose from various frame colors, lens tints, and three interchangeable nose pads for a personalised fit. Whether you’re racing a 5K or tackling an ultramarathon, these running sunglasses offer unmatched comfort, style, and clarity. Worn by professional athletes at the 2025 London Marathon and backed by SunGods Lifetime Guarantee, the Forty2s are a trusted, sustainable choice for serious runners who demand performance without compromise.

The Iris Photochromic lens adjusts to fast-changing light conditions, for no lapse in vision and ultimate focus.
