Callaway Big Bertha B21 Iron Set 4-PW, AW - KBS Max CT80 Stiff Steel Shaft

Callaway designed their legendary Big Bertha shaping with a NEW formula for distance and forgiveness…any way you swing it. It’s a technology package that delivers more ball speed, higher launch and straighter shots for a new level of confidence that you didn’t think was possible.
