The PING G10 XG 8pc. Iron Set features low-toe weighting and large cavity design for high MOI that ensures consistent distance and accuracy. Large, stainless-steel club head has conforming grooves and a wide sole for higher launch angles and reduced spin so you can better control the flight of your ball. Custom Tuning Port (CTP) provides for consistent velocity across the face by stabilizing the hitting area. CTP is made of elastomer for great sound and feel at impact. Wide Sole and deep cavity design place the CG low and back for better trajectory and great forgiveness.
