The Fly Screen whether Dart or National, provides for relief of chest pressure and not much at all for in your face protection. It is a low profile application that does make a difference with chest pressure and if you get relief from flies? Well your lucky! I used one on a 1500 mile ride in the harshest of riding, and it was much better than naked, for certain. As long as you know what your have it is a value especially for the minimalist.
