To keep your view clear in rainy weather, National Cycle developed RainZip, a specially formulated rain repellent treatment for National Cycle’s Quantum hardcoated polycarbonate windshields and other polycarbonate windshields and helmet faceshields.
When rain accumulates in your line of sight, RainZip makes it bead up quickly and blow away, even at speeds as slow as 35 mph.
RainZip comes in a 3-ounce container, enough for two large windshield applications, each lasting three to four months. It also comes with special application cloths. MSRP is $30.95.
