Sunglasses often are extremely curved to provide improved protection against solar radiation. If you want to stow such sunglasses away, they tend to be quite bulky and take up a lot of room. SPIN+STOW means 360° power. With rotating earpieces, FONS sunglasses can be folded flat so that there is room for them anywhere. This new technology consists of several individual components that are held together without a fixed connection and are discretely integrated into the product. FONS sunglasses stand out not only with their rotating earpiece hinges, but also with their lightness, wearing comfort and great stability.
