The set consists of 4-PW (7 clubs)

✖️ Ultra thin face for metal-wood-like performance, resulting in faster ball speeds and much longer, higher-trajectory shots with increased stopping power.

✖️ Hollow body is injected with lightweight foam to create a softer, forged-like feel on every swing with better acoustics

✖️ A groove has been carved out of the internal surface of the face which increases deflection which helps maximise face movement and energy transfer resulting in higher launch and trajectory as well as faster ball speeds.

✖️ Tungsten weighting placed low into the heel and toe sections of head for higher MOI and increased forgiveness

✖️ Chrome plated finish for premium look and increased durability
