GREAT LIGHTWEIGHT MESH JACKET! Compared to many mesh jackets on the market, this one is truly high-airflow. While it doesn't come with a liner or extra beefy materials, is that really what you want out of a mesh jacket? Serious question. Are you wanting a convertible all-around jacket? Or do you want your mesh jacket to be ultra-lightweight, comfortable, still protective, but with the emphasis on airflow, wearability, and comfort? If the latter sounds like you, then the Crossover is for you. Sometimes mesh jackets try to do everything and end up not doing what they were intended for (hot weather riding) very well. The Crossover focuses on just handling hot weather riding exceptionally well. You can always layer up your own inner layers for cool days, but really where the Crossover works great is as a supplement to other garments you have. Maybe you have a leather jacket that is your hard riding jacket and your pretty weather jacket. But that piece just gets too hot for around town summertime rides, or you don't want to lug around your leather jacket when errand running in summer. Here is a relatively inexpensive, quality piece that fills that niche with style and function.
