In this product, the main theme is "dynamic and unbounded" and "dynamic running time". What Ethan Ruan interpreted is "fashion color matching, windbreak design, regardless of the sports moment or city exploration, always has the type" brand connotation, while Li Bingbing interpreted is "trim the body to tailor, the windproof design, sometimes the individuality is unique and the time is full of movement, leads the metropolis movement trend."
