Callaway Men's Big Bertha B21 Iron Combo Set

Features and Benefits:

• Fast Ball Speeds From The First A.I. Designed Big Bertha Irons
  High ball speeds and increased spin robustness from our industry-leading A.I Flash Face Cup. Ball speed is further enhanced by our 360 Face Cup that flexes and releases at impact.

• Improved Turf Interaction From Legendary Big Bertha Shaping
  A club profile that's engineered to give you more confidence over the ball with noticeably wider soles. For easy launch, lower spin and straighter flight, we've added more offset into the head.

• Easy Launch From Our Visible Tungsten Energy Core
  Now you can get higher launch conditions through the set. We've added a significant amount of custom tungsten weighted, so we can deepen the CG with extraordinary precision while still maintaining high ball speeds.
  
  
• Pure Feel From Urethane Microspheres
  Callaway Golfs patented urethane microspheres comprehensively absorb unwanted vibration for
  exceptional feel, while also maintaining fast ball speeds.

Hybrids

• Fast Ball Speeds From Flash Face SS21
  Fast ball speeds across an expansive area in each model and loft, with Callaway Golf's advanced A.I.-designed Flash Face. So you’ll hit it long, even if you miss the center of the face at impact.

• Straighter, Longer Ball Flight From Increased Offset
  Callaway has added more offset to help reduce your slice or big miss. This increased offset helps to promote a straighter ball flight for more distance.

• Enhanced Launch and Trajectory Control From Dual MIM’ed Tungsten Weighting
  Optimized CG for launch and stability from precisely shaped dual MIM’ed tungsten weight.
  
  
• Increased Ball Speed And Easy Launch
  Two internal Jailbreak bars connect the sole and crown, so the face can take on more of the load at impact. For higher MOI in a forgiving shape, we've used a significantly lighter carbon crown so we can redistribute weight.
