Cobra King Speedzone One Length Iron Set

ONE Length technology is a simplified approach by offering matching lengths (37.50�), head weights and swing weights in every iron.
The Cobra KING Speedzone irons deliver ultra-low CG and increased ball speed thanks to a carbon-fibre topline.
Light Zone: Two strips of Carbon Fiber replace steel both on the topline and underneath the topline and saves 3 grams of discretionary weight to be repositioned low to increase ball speed and launch in the 4-7iron.
Stability Zone: Through the use of Speedback shaping Cobra has created a wider body around the perimeter of the club that delivers increased MOI and aids in lower CG.
Power Zone: A new forged PWRSHELL face in the Speedzone irons features an updated E9 face structure that helps to lower the CG and create more return through a deeper undercut speed channel.
Feel Zone: Optimised feel through the creation of a co-molded medallion system that damps vibrations quickly for exceptional sound and feel even on off-center strikes.
Spin Zone: V-grooves are utilized from the 4-6 iron to reduce spin while U-grooves on the 7-PW optimize spin, and wedge-based grooves on the GW and SW to produce maximum spin for shots around the green.
