The Carbon Express Aramid KV™...The ultra strong Aramid KV™ utilizes Dupont Kevlar® to produce the ultimate hunting arrow. For years, Kevlar® from DuPont® has been used in body armor to protect military and law enforcement personnel from bullets. Now, this remarkably light yet incredibly strong synthetic fiber will help hunters shoot better—while setting a new standard in arrow technology, engineering and performance. 5 Times Stronger Than Steel. Pound for pound, Kevlar® fibers are 5x stronger than steel. To take advantage of Kevlar’s incredible strength, the Aramid KV™ is engineered with a layer of Kevlar® between carbon fibers. The result is an arrow that can withstand the force of impact from bone, trees and the ground while maintaining its spine integrity shot after shot after shot.
