Fast initial velocity, lower spin and high launch combine to produce a flatter, less arcing ascent and straight ball flight for exceptional driver and long iron distance. The trajectory profile of the Titleist Pro V1 generates a steep angle of descent into the green and provides Drop-and-Stop? performance on approach shots. 1 dozen balls per box, 4 sleeves per box, 3 balls per sleeve. Made in the USA. Imprinted with the International logo.
