Introduced in 2019, the 1.75" X3 Vane is made of ultra-stiff material for maximum arrow stabilization and quiet flight, with the same profile as the shield cut X Vane. We recommended it for 3D, indoor spots, Fita and Field. The 1.75" (44.5mm) X3 Vane measures 0.38" (10.2mm) in height and weighs an average of 4.4 grains (285.1 mg). Like all Bohning vanes, the base of the X3 Vane is pre-primed for optimal adhesion. Due to the ultra-stiff material, we recommend using an instant glue and/or a fletching jig with high adhesion force such as Bohning's Tower Jig or Multi-Fletcher. Proudly manufactured at the Bohning Factory in Lake City, Michigan, United States.
