Cobra's Max irons share a similar design ethos to the recently released Cobra King F6 irons by using TecFlo technology to create a progressive set with each iron built to do the job at hand.
The Max irons have three different constructions with each club optimised for performance to help the improving golfer hit more greens and lower scores.
The 4 to 8 irons have a half hollow design with a cavity and a hollow in the lower half of the clubhead to create a lower and deeper Centre Of Gravity (CG) that make these irons easier to launch with a great level of forgiveness. This is done using an aluminium cap to replace steel, which frees up 5 grams of weight to be moved lower in the head.
The 9 iron and the Pitching Wedge have what Cobra call a deep cavity undercut design that takes weight from the back of the entire face area and relocating it around the perimeter of the head to increase forgiveness and accuracy.
The Cobra Max Gap and Sand wedges feature a special wedge construction that helps give added versatility and shot control around the greens and in bunkers, to make these difficult shots easier for higher handicappers.
In the Max irons it's not only the construction that changes as you move through the set. The concept of flow can be seen in the visible heel and toe weighting that increases MOI for greater forgiveness in the long and mid irons, whilst the more centralised weight in the shorter irons and wedges helps accuracy and shot making.
The offset incorporated into the heads to make it easier for golfers to square the club up through impact also notably changes through the set. The 4 iron has the maximum offset of 6.3 mm and this decreases as to just 0.8 mm in the Sand Wedge.
The final modification in the Max itons optimises spin and launch conditions for each club using what Cobra calls Progressive Spin Technology. V-grooves are used in the 4 to 6 irons to reduce the spin generated by the long irons to increase distance. U-grooves in the 7 iron to the PW give an optimised spin control for shots that are approaching the green, whilst the GW and SW have wider spaced grooves for extra spin for shots around the green.
The Cobra Max irons are designed to dovetail with the Cobra Max hybrids at the top end of the bag to allow players to pick the best combination for them in terms of gapping and forgiveness on the longer fairway shots.
