Compression measures how much a ball deforms at impact. Match it to your driver speed and the ball returns the energy you put into it; miss the range and you either leave distance behind or lose the soft feel you paid for. The full golf ball compression chart ranks every ball we track, and the golf ball finder narrows it to your own speed.
Who the Kirkland Signature suits
The viral Costco ball — genuine 3-piece urethane at $22/dozen. We tested it against Pro V1 and found 90% of the performance. Costco publishes no compression figure, so this is MyGolfSpy Ball Lab's measured average for the V3 (91 on the yellow sample, 92 on the white).
