Designed with input from the Drury Outdoors Team, the BowMadness arrows use radial X Weave technology taking carbon-arrow technology to an entirely new level. A patented computer process wraps individual carbon fibers to create a weave pattern and an arrow that is faster, stronger and straighter than conventional carbon arrows. Straightness and weight tolerance within +/-.003 inches and +/- 5 grains. Arrows are full length with inserts loose. Fletched with Fusion Vanes. Size: 300. 6-Pack.
