Srixon's first super game improvement iron, the ZXiR HL, is engineered to help slower swing speed players maximize launch, carry distance, forgiveness, spin, and stopping power while retaining the confidence-inspiring profile and clean topline the ZXi family is renowned for. The ZXi lineup is acclaimed for its pure feel, and thanks to i-ALLOY, an all-new steel created by Srixon, the ZXiR HL continues the legacy. Markedly softer than the 431 steel commonly used in the super game improvement category, i-ALLOY delivers a rewarding impact sensation without sacrificing the strength and durability required to produce such a high-performance iron. MainFrame, Srixon's artificial intelligence developed network of milled grooves and channels behind the face, is the driving force behind the ZXiR's robust distance and forgiveness capabilities. By removing mass from the face, this variable thickness pattern maximizes the face's capacity to flex and rebound, resulting in powerful ball speeds on center strikes and remarkable forgiveness on mishits. Additionally, the newly eliminated mass yields weight savings, which Srixon redistributed around the head's perimeter, further enhancing forgiveness, MOI, and stability. Stock shaft options include KBS' steel 80HL and MAX Graphite Iron offerings.
