The Santini Nebula is a collapsible windbreaker in a women's design that folds into its own pocket so you can keep it with you at all times. This self-contained system is also used as product packaging, reducing plastic waste. The jacket has been made from Tovel Bio Zerowind®, a double-layer membrane fabric that is ideal for protection from wind and light rain. In addition, it is comfortable and warm. A reflective strip on the back pocket will enhance your visibility and therefore safety.
