Tungsten long irons
Three tungsten weights for higher, softer-landing long irons.
Build Options
Progressive tungsten-weighted irons designed with Tommy Armour III
Sub 70 Golf · IronsThe Sub 70 TAIII Forged Irons are the product of two years of collaboration with Tommy Armour III. The long irons carry three tungsten weights low in the head for a higher, softer-landing flight, the mid irons shift mass upward for a more piercing trajectory, and toe weighting in the mid and scoring irons resists rotation for better face control. The scoring clubs are built for a tight, wind-cheating flight that stops quickly.

Why golfers choose it
