With their wide-sole and low-profile head design, these Cobra SZ Irons offer superior forgiveness, maximum distance and great feel. The extreme low, back CG (center of gravity) provides high launch, while the heel and toe distributed weight maximizes accuracy. The irons have a full back cavity plate with a urethane insert to give an enhanced feel. Premium Aldila DVS HL shafts generate faster clubhead speeds for higher launch and increased distance.
