The 2014 Cobra BiO CELL Irons are packed with game-improvement technology. Deep undercuts, large unsupported faces, and tungsten weighting technology provide golfers with extreme distance and forgiveness. The long irons (3-7) have two 10-gram tungsten weights located in the outer-cavity ports to make the irons more stable on mishits, increasing forgiveness. The short irons (8-GW) have their two 10-gram tungsten weights located in the inner-cavity ports, increasing workability and feel, a much-valued attribute for short irons. Get your new 2014 Cobra BiO CELL irons from 2nd Swing and go through our online fitting process during your purchase so you’ll start sticking your irons close right out of the box.
