Cleveland CG4 irons. Made from Cleveland Golf's own CMM metal, the CG4 irons have 17 times more carbon than traditional steel for greater vibration absorption and is also 10% less dense which allows for 25 grams of weight to be redistributed to get the ball airbone sooner. Clevleand CG4 irons feature a cavity back which gives them larger sweet spot for added forgiveness on off-centre hits. These irons also come standard with Cleveland Golf's patented V.A.S technology to help further reduce unwanted shock. Feel can't be taught - but it can now be bought!
