Zebra Trophy is built with the new, proprietary Trophy Process which leverages over 20 years of experience building and testing strings for the world’s top bow manufacturers & champion, professional archers. The Trophy Process is a proprietary pre-conditioning process that guarantees no serving separation and the shortest “shoot-in” time of any premium bowstring. Every Trophy bowstring and cable that leaves the Zebra shop has been pre-stretched, measured and tested to achieve the highest level of consistency in the industry. Shooters can rest assure that the string they order will fit their bow’s unique specs and improve their performance. Made in the U.S.A.
