Kirkland Yellow vs White: Two Factories, Two Different Golf Balls (2026)

Quick answer

Kirkland yellow vs white at a glance

Spin ranks are from MyGolfSpy’s 2026 ball test, a 48-ball robot-controlled study published in August 2026. The two Ball Lab scores come from teardowns run two and a half years apart, which matters — see the quality section below.

Why one product name covers two balls

Costco contracts its ball production out, and as of 2026 it uses two plants at the same time. MyGolfSpy’s Ball Lab places the white Performance+ V3 in Vietnam, at the SM Parker factory that also makes the PXG Xtreme. Its July 2026 teardown of the yellow lists the factory as SM Global in China, a plant that also turns out balls for Snell and Vice.

Two production lines, two sets of tooling, two batches of raw material. Costco sells the output under one name at one price, and the box tells you which one you’re holding if you read the country of origin.

Golfers spotted this before the robots did. The comment thread under that January 2024 white-ball teardown is full of readers asking MyGolfSpy to test the yellow, one of them calling it “the best kept secret in the game.” When MyGolfSpy finally split the two colors in 2026, its stated reason was exactly that: “As readers have noted, the yellow and white versions of the ball are produced in different factories.”

What the robot measured

MyGolfSpy tested driver and 7-iron at three swing speeds each, six conditions in total. The yellow beat the white in five of them, usually by a wide margin.

Off the driver at the top speed tested, the yellow ranked third-highest for spin in a 48-ball field. The white ranked 13th. Drop to mid speed and the yellow sits ninth, the white 17th. MyGolfSpy’s own note on the pair is blunt: the white “sits well back of it at both, 17th and 13th, which is its own kind of finding for two balls sold under one name.”

The iron numbers run the same direction. Summarizing the full-swing portion of the test, MyGolfSpy wrote that off both the driver and the iron, at every speed tested, the yellow “sits inside the top 10 for spin. The white version does not, landing between 13th and 17th in five of the six conditions.” At slow iron speed the yellow came out fifth, behind only the Vice Pro Plus, Srixon Z-Star Diamond, Callaway Chrome Tour X and Titleist Pro V1x (~102). That is expensive company for a $20 ball.

Higher spin isn’t free, and the test showed the bill. At mid driver speed MyGolfSpy grouped the yellow with the high fliers and observed that the longest balls at that speed were not the highest-flying ones. If you already fight a ballooning drive, the yellow’s spin is the wrong kind of help. The compression chart covers where that trade starts to cost carry.

The one condition where they match

Slow driver speed is the exception, and it’s worth knowing if it describes your swing. There the white finished ninth for spin and the yellow eighth, on what MyGolfSpy called “effectively the same number.” Its verdict on that single condition: “this is the one condition where the two Kirklands behave alike. At every other speed and club we tested, they’re 10 or more places apart.”

MyGolfSpy also singled out the white here as the value standout, the ninth highest-spinning ball in the test and “by some distance the most spin available at that price.” So a golfer swinging the driver in the low 80s who already has a box of white balls in the garage hasn’t made a real mistake. Everyone faster has.

Greenside is a problem for both

The color question gets most of the attention, and it distracts from a bigger change in this ball. Kirkland built its reputation on tour-level wedge spin at value pricing, and the 2026 numbers no longer support that.

On a 35-yard wedge shot, MyGolfSpy found the white Kirkland spun less than the highest-spinning ionomer ball in the test, with the yellow effectively tied with it. Across the full field, urethane balls averaged roughly 1,250 rpm more greenside spin than ionomer ones, described as the largest cover-related difference the test measures anywhere. MyGolfSpy’s summary line is the one to carry out of this: “You need urethane to get greenside spin but it’s not guaranteed just because you’ve bought urethane.”

Both Kirklands have a urethane cover. Neither is banking the advantage that cover is supposed to buy. If your scoring comes from spinning wedges inside 50 yards, price this ball against a premium urethane option on short-game merit and expect to pay for the difference. Our urethane vs. ionomer breakdown covers what that cover material is supposed to deliver.

Quality control, with an honest caveat

The teardown numbers favor the yellow, though not as cleanly as a straight 84-versus-45 comparison suggests.

MyGolfSpy’s July 2026 Ball Lab report on the yellow scored it 84, a grade B, built on a 100% good-ball rate: zero defects across 36 balls from three boxes. Compression averaged 91.0 with a 6.7-point spread, better than the database average of 9.7. Diameter consistency graded C and compression symmetry C+, the two categories that kept it out of B+ territory, and the ball runs slightly large and light for a urethane model.

The white’s only Ball Lab teardown is from January 2024, on the 2023 ball, and it scored 45 — 29 points below the database average at the time. Compression ranged from 88 to 103 across that sample, a 15-point spread rated “Poor,” with 3% of balls over the USGA weight limit.

Those two reports are two and a half years and two model years apart, so treat the gap as suggestive rather than a controlled head-to-head. What’s solid is the current evidence: the most recent teardown of a Kirkland ball is the yellow’s, and it came back clean.

Which one to buy

• Swing speed above roughly 85 mph: buy the yellow. It won five of six full-swing conditions, holds the recent clean quality result, and costs the same.
• Slow driver speed, under about 85 mph: either color works on the data, though the ball’s ~95 compression is firm for that swing regardless. The swing-speed guide covers what fits better down there.
• You score with your wedges: neither. Both now spin at ionomer level from 35 yards.
• You already own white boxes: play them. The gap is real on a robot; it will not be the reason you shot 92.

What this doesn’t mean about colored balls

The Kirkland result is a factory story wearing a color as a name tag. It says nothing about yellow balls generally.

Pigment on any modern ball is blended into the cover rather than painted on, so the dimples and aerodynamics match the white version. MyGolfSpy uses a yellow Pro V1 as its control ball for exactly that reason, noting that differences between the yellow and white versions of that model “are small and often statistically insignificant.” Buying a yellow Titleist Pro V1 (~92) or a yellow Srixon Z-Star (~81) gets you the same ball you’d get in white, with better visibility.

Kirkland is the exception because Costco happens to source its two colors from two plants. Our full guide to yellow and colored golf balls covers the vision science behind why yellow tracks best, and every color on the USGA and R&A conforming list is legal for tournament play.

The next step

The yellow Kirkland is a strong full-swing ball at an unusual price, with a short game that no longer justifies the old reputation. Whether that trade works for you depends on your swing speed and where your strokes actually come from. Run it through the BallCaddie fitting quiz — about 90 seconds, scored against the full ball catalog — or compare any two balls side by side before your next Costco run.

Key takeaways

• The yellow and white Kirkland Performance+ are built in different factories — SM Global in China and SM Parker in Vietnam — and sold under one name at one price.
• MyGolfSpy’s 2026 robot test scored them as separate balls: the yellow inside the top 10 for full-swing spin in all six conditions, the white 13th to 17th in five of them.
• Off the driver at top speed the split is 3rd versus 13th of 48 balls.
• Slow driver speed is the only condition they match, finishing eighth and ninth on effectively the same spin number.
• Greenside, both have slipped to roughly ionomer level from 35 yards, against a ~1,250 rpm urethane-to-ionomer average gap.
• The yellow holds the recent clean Ball Lab result (84, grade B, zero defects across 36 balls), though the white’s only teardown is two and a half years older.
• Color is doing none of this work. On every other ball on the market, yellow and white are the same ball.
