Callaway Big Bertha B21 Hybrids are Callaway's easiest to launch hybrids, built for players looking to unlock their inner distance. The hybrid's larger head volume and increased offset help rid you the big miss, resulting in longer, straighter shots. As always, Callaway packs all off their industry-leading ball speed technologies in the B21 Hybrid. A.I. designed Flash Face SS21 technology provides faster ball speeds across the face, even on misses. To boost speeds further, Jailbreak Technology connects the sole and crown, allowing the face to take more of the load at impact. Callaway's T2C carbon crown is extremely lightweight, allowing dual MIM'ed tungsten weights to be inserted in the sole. Rearranging the club's weight significantly increases stability, forgiveness and launch conditions, so you can hit consistently great shots.
