    Description

    The Big Bertha OS Irons are revolutionary in their construction and are full of technological club advances. These irons feature Callaway’s strong and light weight EXO-AGE head design that improves ball speed and forgiveness. The Face Cup 360™ on the faces of the clubs act like a spring on shots struck in the center, or low on the face, in addition to increasing ball speeds of off-center strikes. The Big Bertha OS Irons also feature Tungsten-Loaded Standing Wave technology and a lower center of gravity for longer carrying shots.

    Features

    • Designed with EXO-CAGE technology to be strong and light
    • Revolutionary ball speed from next generation Face Cup 360™
    • Tungsten-Loaded Standing Wave technology for higher launching, longer carrying shots
    • Lower center of gravity for increased control

    Technology / Specs

    Ball speed and forgiveness are enhanced in the Big Bertha OS iron set with an Exo-Cage and next generation 360 Face Cup. The Exo-Cage is light and strong, allowing the weight to be shifted to positions in the head that help forgiveness. The 360 Face Cup increases ball speed and distance on shots hit all over the face.

    Callaway increases the launch angle in the Big Bertha OS iron set by placing a “Tungsten-Loaded Standing Wave” in the sole of the club. The weight lowers CG and raises launch.

    The Big Bertha OS iron set also has a progressive CG throughout the set. The CG location lowers in each club as the loft lowers. This gives longer irons higher launch so they can carry longer and land softer.
