Why it flies straight

Every golf ball spins, and a tilted spin is what bends a shot into a slice or a hook. The Ultimate Straight is shaped to keep its spin from tilting, so up to 75% of that curve never happens. Scroll to see how.

Polara: flies straight, guaranteed.

  1. 01

    One step: point the arrow

    The arrow is the only instruction. Point it down your target line and the ball’s poles sit left and right of it. Every feature you’re about to see depends on that one small step.

  2. 02

    Less lift, less curve

    Dimples grab the air and lift a spinning ball. Tilt that spin with an open clubface and the lift leans sideways: that’s your slice. Polara makes the dimples around the equator shallower, so there is less lift to lean.

  3. 03

    Deep dimples at the poles

    Both poles are ringed with deep dimples. Less drag, and less material at the ends of the ball, which leaves more of its weight around the equator. That is what gives the ball a favorite way to spin.

  4. 04

    Backspin stays backspin

    A straight shot is pure backspin: the ball turning on an axis that lies flat across the fairway. That is exactly the axis this ball prefers, so an open or closed face tilts it less, less spin goes sideways, and the ball holds its line.

  5. 05

    The cover does the steering

    Everything you just saw is cut into this 0.073″ shell of soft ionomer: the shallow band and the deep poles. It also grips the clubface for a little more spin.

  6. 06

    The core does the distance

    1.535″ of soft polybutadiene rubber. Compression 85, soft enough to squash on a normal swing and spring the ball off the face. Two pieces, and the dimples do the rest.
