Big Bertha OS Irons

Game-Changing Distance

By incorporating new clubhead construction with next-generation 360 Face Cup technology, the Big Bertha OS Irons are extremely forgiving and easy to launch. The revolutionary Exo-Cage design is super lightweight and strong, which allows the weight to be repositioned to promote forgiveness and ball speed across the face, giving you more distance on every swing.

Features and Benefits

  • New Exo-Cage technology positions more weight in strategic locations to increase forgiveness and helps next-generation 360 Face Cup function more efficiently
  • Next-generation 360 Face Cup technology elevates clubface COR closer to the USGA limit to produce even faster ball speeds and more distance
  • Tungsten-Loaded Standing Wave technology in the sole lowers the center of gravity to promote higher launch for longer carry and more ball speed low on the face
  • Progressive Center of Gravity technology entails moving the CG location progressively lower in each head, promoting higher launch and long carry in the long-irons and increased control in the short-irons
  • Senior model is lighter in overall weight, with more loft to promote faster ball speed and higher launch angle to make it easy to get the ball in the air

Saved money!
I am living in Southern California. I bought that Callaway Big Bertha Os Irons. I did not have to pay Shipping and CA Tax. Great!
Straight and long
Without a doubt the longest irons I've ever hit. The ball really pops off the face and has a nice trajectory. Good distance spacing between clubs.
