The Kirkland Golf Ball Is $19.99 A Dozen. Ball Lab Found The Catch.

Compression is a measure of how much force is required to deform a golf ball. The higher the number, the firmer the ball. Consistency matters because a ball that compresses differently from shot to shot produces different results from shot to shot. Ball Lab measures every ball individually and tracks both the average and the spread across the sample.

The 2025 Kirkland Performance + v3.0 averaged 92, in the firm range of our database and comparable in compression to the Callaway Chrome Tour and TaylorMade TP5. Compression consistency graded at C+ with a delta of 10.5 points and a spread running from 87.0 to 97.5, slightly wider than the database average of 9.6. Ball-to-ball speed variation is possible across that range.

Ball Lab also measures compression symmetry which tracks how evenly compression is distributed across three points on each individual ball. Is each ball consistent within itself? The Kirkland averaged 3.0 points of deviation against a field average of 1.9, grading at D. Individual balls show more internal compression variation than most of the balls in this test series, meaning the three measurement points on a single ball don’t always agree.

The charts below detail the compression measurements in our sample.

Weight consistency is another metric Ball Lab tracks. Even small differences across a dozen balls can translate to inconsistent ball flight. Ball Lab weighs every ball to four decimal places.

The 2025 Kirkland Performance + v3.0 averaged 1.6097 ounces across 36 balls, in the average range of the database. Every ball cleared the USGA maximum of 1.6205 ounces with a range running from 1.6018 to 1.6201 and a standard deviation of 0.0040. The ball that came in at 1.6201 cleared the limit but left essentially no margin. Box 1 showed the most variation of the three.

Weight consistency grades out at C.

The charts below detail the weight measurements in our sample.

A ball that isn’t uniform in shape can move offline on the putting green or produce inconsistent flight in the air. Ball Lab measures each ball across multiple axes to get a true picture of its shape.

The 2025 Kirkland Performance + v3.0 averaged 1.6831 inches, above the USGA minimum of 1.680, with a roundness deviation of 0.0019 inches. Every ball cleared the minimum. The diameter data does show a shape bias but in the opposite direction from what we saw in the Snell PR4: 29 of 36 Kirkland balls measured consistently thicker through the seam than at the poles. Box 1 was the least consistent of the three at an SD of 0.00147 while Box 3 was the tightest at 0.00043.

Diameter consistency graded out at C.

In the 2026 MyGolfSpy Golf Ball Test, the Kirkland Performance+ v3.0 White showed up as one of the more interesting data points in the field. Off the driver at high swing speed, it finished inside the top 20 for ball speed, but fell toward the bottom third for total distance. It points to a flight profile that doesn’t fully capitalize on the speed it generates.

The white version also behaved noticeably differently from its yellow counterpart throughout the test, trailing the yellow Kirkland by 10 or more places in five of the six driver and iron conditions tested.

Off the driver at low swing speed, the white version was the standout, finishing ninth highest-spinning in the test and the most spin available at its price point. Around the green, though, greenside spin has dipped compared to earlier versions of the Kirkland. For $19.99 per dozen, the performance picture is competitive but uneven depending on the condition.
