Callaway's Big Bertha B21 irons feature industry-leading Flash Face Cup, which flexes and releases at impact, to create high ball speeds and increased spin robustness off of every iron in the set.
This club profile that golfers love is engineered to give you more confidence over the ball with noticeably wider soles and more offset to lower spin and deliver straighter shots.
Visible custom tungsten weighting lowers the C.G. location in each iron for high launch without sacrificing ball speeds.
Patented urethane microspheres absorb unwanted vibration for exceptional feel.
