The secret behind the Zebra Z-S Twist bowstring is the patented Z-S Counter-Twist Technology. The strands in the Z bundle are twisted counter-clockwise while the strands in the S bundle are twisted clockwise. The two opposing bundles are then twisted together. When you draw your bow, the string has no twist bias and therefore pulls back straight, virtually eliminating peep sight rotation.

Competition is the Ultimate Test   Professional tournament archers and bowhunters who make their living in the field agree, Zebra Z-S Twist bowstrings are the best performing bowstrings in the world! When it comes to product performance, the ultimate proving ground is competition....over the last 6 years, Zebra Z-S Twist bowstrings have won over $5,500,000...far more than any other bowstring.
