Callaway found a new path to power with Big Bertha OS Hybrids/Irons. The ultralight yet ultra-strong Exo-Cage allows more weight to be strategically positioned lower in the head, resulting in superb forgiveness, while next-gen 360 Face Cup™ technology creates more ball speed and distance. Tungsten-Loaded Standing Wave technology in the sole progressively lowers CG, promoting high launch, longer carry, and greater control on approach. Super-charged hybrids unlock even more distance and forgiveness.
