COASTEX™ is our own custom-developed fabric, created in close collaboration with our Italian partner. It offers a unique combination of 100% waterproof protection, breathability, and a soft, natural touch. Made from organic cotton and recycled polyester. All seams are sealed with a durable, chemical-free tape from Italian Framis. Inspired by the dense cottons of vintage outerwear but engineered for modern performance with lowest possible environmental impact in mind.
