COBRA S3 4 PW GW Iron Set with Steel Shafts

Cobra S3 4 PW, GW Pro Iron Set with Steel Shafts The Cobra S3 Iron Set has E9 Face Technology and multi material design, which combine to optimize all around performance in each individual iron of this set. E9 Face Technology is a new, advanced system that creates a larger sweet zone for increased distance and accuracy. A progressive cavity design, which has a new back cavity shape and optimized face thickness design, progresses from elliptical long irons to circular short irons to optimize distance and feel based on typical golfer impact patterns. A special high strength composition of steel and alloy in the long and mid irons allows for a thinner, hotter face, increasing coefficient of restitutution and ball speed. A new hidden internal polymer topline and full cavity TPU thermoplastic urethane combine to optimize weight distribution and dampen vibration for superior feel and distance. A stepped crescent sole design narrows in the toe and heel to provide superior turf interaction, promoting more consistent distance and accuracy. The Baffler style hybrids in this set promotes more forgiveness and a higher ball flight than standard long irons and provide more consistency and versatility.
