## Description

This new Black Widow features the Aggression Hybrid coverstock, which is the same chemical base as the cover found on the Rip’D. Wrapped around Hammer’s iconic Gas Mask core, this Widow is designed to perform best on medium to heavy oil. This Widow’s deadly backend bite and pin action will be sure to turn some heads.
With Hammer’s patent-pending carbon fiber outer core.
Hammer recommends Tough N Tacky cleaner to keep the Black Widow Black/Gold performing at its best.
