HThe best urethane cover since the 80’s wrapped around the best core of our generation is sure to make for a special ball motion!
Our Urethane cover is the main ingredient in this masterpiece. Unlike modern covers that produce a violent reaction at the breakpoint, this proven staple is all about giving the user ultimate control of the entire lane. The immediate success of our real, thick shelled Black Urethane had our fans begging for more! To satisfy their desires, we have developed the perfect combo, thick shelled coverstock to compliment the Black Widow’s legendary Gas Mask core . Old school technology with new school hitting power. Because nothing hits like a Hammer.
