The Ice Vane is designed for Fita and Field archery. Its length and ultra-low profile are ideal for stabilizing small diameter, heavier-spined arrows during windy conditions. The Ice Vane measures 3" (76.2mm) in length, 0.3" (7.6mm) in height, and weighs an average of 6.5 grains (421.2 mg). Like all Bohning vanes, the base of the Ice Vane is pre-primed for optimal adhesion. Proudly manufactured at the Bohning Factory in Lake City, Michigan, United States. U.S. Patent 8,388,474 B1
