UltiSoft is true to its name as the ultimate golf ball for softness and feel. It's the lowest compression ball in our lineup, delivering unmatched performance on every strike. And now, thanks to the FastLayer Core, UltiSoft off-the-tee performance just got longer. FastLayer Core With a soft center that gradually transitions to a firm outer edge, the FastLayer Core gives UltiSoft incredible softness and great distance off the tee. 338 Speed Dimple Pattern To get more distance overall and better performance in the wind, Speed Dimples reduce drag at launch and increase lift during descent. Soft, Thin Cover Provides more greenside spin and softer feel on all pitches, chips and putts.
