HZRDUS Smoke Green RDX is the stiffest and lowest launching/spinning model in the HZRDUS RDX family. RDX Green is the next evolution of the popular HZRDUS T1100 and is designed with four different modulus carbon fibers to optimize performance and feel. Featuring a counterbalanced design, RDX Green allows for longer playing lengths or for mass to be added to the clubhead to increase ball speed and MOI.
