The Griffin® Vane is truly a revolutionary vane! Bohning's first vane designed exclusively for olympic recurve archers, the Griffin Vane boasts all the performance benefits of a mylar-type vane (e.g. spin wing) without the drawbacks! Its twisted ribbon design aids in immediate arrow rotation and the minimal surface area resulting from the cut-out profile provides a stable & accurate flight in variable, constant, and zero wind shooting scenarios. Weighing only 1.2 grains, it's made of extremely durable, nondeforming vane material - you'll never have to hear that distressing buzzing sound of your mylar vane tearing loose from your arrow mid-flight again! And you'll be able to spend more time actually shooting as you say good-bye to the daily grind of constant refletching - the Griffin Vane has a straight base that can be fletched with a standard Pro Class Style Jig using glue or tape. Just use the included clamp adaptor!
