This innovative new system is two windshields in one! Run it with the lower section as a half windshield for open air driving. Run just the upper section for great ventilation while still blocking wind and dust from hitting your face. Use both sections for full windshield protection. The low mass seam minimizes visual distortion and is sealed with a gasket to block water intrusion. Constructed of thick .220” impact resistant optical acrylic. A full, half, and upper windshield.
