Colorado-based optics brand, Zeal manufactures sunglasses and ski goggles for nature enthusiasts and offers a wide range of products for everyone. The development team is lucky to live close to nature and get the chance to directly design and test performance-oriented products for outdoor activities. The brand uses plant-based materials for its frames and lenses, a great alternative to plastic. At Glisshop, we offer a wide range of Zeal products organised by activities and styles to help you find what you’re looking for.
