Trevor Brazile was relentless in his demands for the traditional Xplosion. His dedication coupled with the work of the Cactus rope makers, made the best-selling non-core rope in the industry. The increased amount of poly adds weight and body to the center of the Xplosion. This blend places the emphasis of your swing on the tip and adds durability to the rope. The Xplosion is part of Trevor Brazile’s Relentless™ line. 4 strand, nylon poly blend.
