Signature Performance+
A three-piece urethane-covered (soft, grippy cover) ball sold only at Costco, $29.99 per two dozen at the Costco warehouse ($39.99 shipped online). MyGolfSpy's 2026 robot test measured the yellow and white versions separately: they come from different factories (yellow: SM Global in China; white: SM Parker in Vietnam) and perform differently — the yellow ranked top-five in the 48-ball field for full-swing spin while the white ran 10+ spots lower in most conditions. The trade-off: on short greenside shots both versions now spin closer to the best ionomer balls than to premium urethane. If you buy Kirkland, buy the yellow.
What do these specs mean?
Compression
How soft the ball feels. Lower numbers (70–80) compress easier and help slower swings get distance. Higher (90+) rewards faster swings.
Cover
Surlyn is tough and cheap — great for distance and durability. Urethane is softer and grips wedges for more spin around the green.
Layers
2-piece: simple, long, straight. 3-piece and 4-piece add layers for more feel and spin control on approach shots.
Trajectory
How high the ball flies. Low = flatter flight with more roll. High = peaks up and lands soft. Mid = balanced.
Spin
Low spin = straighter shots, less curve, more roll. High spin = more control and stopping power on the green (but also magnifies slices/hooks).
Tier
Price bucket. Value = budget-friendly distance balls. Mid = solid all-around. Premium = tour-level spin and feel, costs more per dozen.
Best For
Try a sleeve first — ~$5 for 3 balls before committing to a dozen.
A three-piece urethane-covered (soft, grippy cover) ball sold only at Costco, $29.99 per two dozen at the Costco warehouse ($39.99 shipped online). MyGolfSpy’s 2026 robot test measured the yellow and white versions separately: they come from different factories (yellow: SM Global in China; white: SM Parker in Vietnam) and perform differently — the yellow ranked top-five in the 48-ball field for full-swing spin while the white ran 10+ spots lower in most conditions.
Who It’s For
The Kirkland Signature Performance+ is built for faster swing speeds (105 mph and above). It suits golfers who prioritize budget friendly, mid handicap, recreational, frequent ball losers. It is Costco’s single in-house golf ball, sold only in two-dozen boxes.
Feel
With a compression of 95 and a urethane cover, feel is firm and explosive — rewards fast swings with maximum energy transfer and a click at impact.
Spin Profile
Expect balanced driver spin — neither squirrelly in the wind nor knuckling short, though which box you grab matters: the yellow version measured top-five in the 48-ball field for full-swing spin, the white 10+ spots lower in most conditions. Around the green, the honest read is less flattering — on short greenside shots both versions now spin closer to the best ionomer balls than to premium urethane.
Trajectory & Construction
A mid-flight window — versatile across course conditions. The 3-piece construction uses a three-piece design — one mantle layer manages driver spin while the cover handles wedge grip. Works best in warmer conditions.
Price & Value
At $29.99 per two dozen in the warehouse — about $15 a dozen — the Signature Performance+ is a value pick. Expect distance and durability over tour-grade wedge spin.
Buy it if
- You swing 105+ mph and you want a urethane ball for a quarter of the tour-ball price.
- You can buy the yellow version — it is the one that measured with the best balls in the field for full-swing spin.
- You lose more than a sleeve a round and don’t want to grimace every time.
Skip it if
- Your swing speed is under 95 mph — you won’t compress it enough to get the intended distance.
- Short greenside spin is your scoring advantage — a premium urethane ball still bites harder from 20 yards and in.

Who should play the Kirkland Signature Performance+?
The Kirkland Signature Performance+ is built for faster swing speeds (105 mph and above). It suits golfers who prioritize budget friendly, mid handicap, recreational, frequent ball losers.
What swing speed is the Kirkland Signature Performance+ designed for?
It is built for faster swingers (105 mph and above) who can fully compress the core.
Does the Kirkland Signature Performance+ have high greenside spin?
Moderately. The urethane cover grips on full wedges, but on short greenside shots the 2026 robot data puts both the yellow and white versions closer to the best ionomer balls than to premium urethane.
Is there a difference between the yellow and white Kirkland balls?
Yes. They are made in different factories — yellow at SM Global in China, white at SM Parker in Vietnam — and the 2026 robot test measured them separately. The yellow ranked top-five in the 48-ball field for full-swing spin; the white ran 10+ spots lower in most conditions. If you buy Kirkland, buy the yellow.

Not especially. The firmer construction can feel harsh and lose carry below 55°F — consider a softer-compression ball for winter rounds.

About $15 a dozen at the Costco warehouse ($29.99 per 2-dozen box). Costco.com lists the same box at $39.99 shipped.
