Callaway Big Bertha OS Hybrid Left Hand Regular 4

Callaway Big Bertha OS Hybrid are designed for super-charged distance and ultimate forgiveness, with a deeper body, larger and faster face, and next-generation Face Cup technology. Next-generation Hyper Speed Face Cup promotes faster ball speed across the face, especially on off-center hits. Designed with the assistance of aerodynamic experts, Callaway’s Speed Step Technology improves airflow to promote faster clubhead speed for more distance. Refinements to the head design include: 1) Longer heel-to-toe length that allows for a larger and more forgiving face. 2) Deeper body for increased MOI and stability. Together they make the BBOS hybrid remarkably easy to hit. Optifit hosel technology lets you easily choose from eight loft and lie settings to dial in the launch angle and shot shape that promote maximum distance and accuracy with your swing. Loft can be set to -1°, S (Stated), +1°, +2°. Face angle can be set to Neutral or Draw. The Dual Runner Sole design promotes better turf interaction for more consistently solid contact.
