Imitation barred coloring. This is the First Modern Feather for Modern Bowhunters! This feather was cut from a specific location in the full length feather allowing it to be "Whisper Quiet" as it guides your fixed blade broadhead and arrow down range to your intended target. This feather is 2" long and averages 13 mm tall at its highest point. It will average a mere 1.7 grains in weight and should be used by bowhunters using modern equipment and target archers. This feather can be used on all types of arrow shaft materials.
