Hat of down jacket / hat

The conceptual design stems from my personal experience. In winter, I often wear down jacket and a big hat, integrated with the jacket and large enough to block the view of the two sides. It’s very inconvenient to see whether there are any cars at the back. It’s concerned about the safety of a pedestrian. So I design the hat for my down jacket. The hat is characteristic of transparent and soft materials at its two sides, which can preserve heat and stop wind. The two sides can be clearly seen and the view is broadened and safer with the hat.
