In this video, we dive into the science behind waterproof cycling jackets and explain why the legendary Gore-Tex ShakeDry technology has been phased out. We explore the health and environmental concerns surrounding PFAS, often called "forever chemicals," and how they might be affecting you and the planet. Finally, we look at the next generation of eco-friendly waterproof alternatives and see if new technology can finally match nature's own water-repellent designs.
