The new Pro V1 Golf Balls represent the culmination of two years of meticulous research and development by Titleist's industry-leading R&D team. Through a complete reformulation of the core, Titleist's latest flagship offering boasts a measurable ball speed gain and increased spin in scoring clubs, all while maintaining low spin off the tee. The Pro V1, the optimal choice for most players, is softer, spins less, and produces a flatter trajectory than Pro V1x.
