Cleveland CG4 Cavity Backed CMM (Carbon Metal Matrix) Irons with Graphite Shaft:

Designed for players of all abilities, and offering exceptional feel and performance, the Cleveland CG4 irons represent the biggest breakthrough in golf since stainless steel drivers were deemed obsolete by the use of light-weight titanium.

• Cavity back design with a wider sole for a lower and deeper center of gravity and a higher moment of inertia to promote stability and forgiveness at impact
• Features a mid-size blade with progressive offset profile throughout the set

CMM (Carbon Metal Matrix)

• 17 times more carbon than traditional 8620 and 1020 carbon steels
• Additional carbon dampens vibration
• 10% less dense and 15% softer than traditional carbon steel
• The lower density and softer feel helps to create a more forgiving and softer feeling club than any other club in its class
