Callaway S2H2 Iron Set
The Callaway S2H2 irons provide higher launch and higher spin for softer landings with better feel. The "Short, Straight, Hollow Hosel" or S2H2 allows less weight in the neck of the club and helps keep weight low in the club to promote higher launch and spin. The hollowed hosel allows the shaft to extend to the sole of the club, giving a more stable feel at impact.
