Kirkland Signature Performance+ Golf ball compression, specs & review
The Kirkland Signature Performance+ is a 95-compression, 3-piece golf ball with a urethane cover, mid spin and a mid flight. 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 Global 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.

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 Global 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 a firm 95-compression ball with no published target swing speed. 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, with a crisp click at impact that fast swingers tend to like.
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
The white version flies low: MyGolfSpy measured the lowest driver launch of all 48 balls at 102 mph (12.5 degrees), and it still peaked at about 85 feet. It is a three-piece ball, core, mantle and urethane cover, made for Costco by SM Global, with the yellow and white versions coming out of different plants. 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. In that robot test the white ball’s 35-yard wedge spin was about 4,320 rpm, 40th of 48, so you are buying a urethane price break, not urethane wedge spin.
Buy it if
- You want a urethane ball for a quarter of the tour-ball price and do not mind a firm feel.
- 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 a couple of balls a round and would rather do it at $15 a dozen than tour-ball money.
Skip it if
- You want a soft feel. At 95 compression it feels firm, even though firmer balls tended to be faster off the driver at every swing speed in robot testing.
- Short greenside spin is your scoring advantage — a premium urethane ball still bites harder from 20 yards and in.

Frequently Asked Questions
What is the compression of the Kirkland Signature Performance+ golf ball?
The Kirkland Signature Performance+ has a compression of about 95, which puts it in the high-compression range. MyGolfSpy’s 2026 gauge read the white version at 94 and the yellow at 96, so we list 95 for both. At 95 it is a firm ball, and in MyGolfSpy’s 2026 robot test that firmness came with tight dispersion: the white version’s driver pattern was 42 to 43 percent tighter than its comparison group at 86 and 116 mph. It is one of several specs the BallCaddie fitting quiz weighs against your swing speed, usual miss, feel preference and budget.
Who should play the Kirkland Signature Performance+?
The Kirkland Signature Performance+ is a firm 95-compression ball with no published target swing speed. It suits golfers who prioritize budget friendly, mid handicap, recreational, frequent ball losers.
What swing speed is the Kirkland Signature Performance+ designed for?
Costco does not publish a target speed, and the robot data cuts both ways. At 86 mph the white ball carried 197 yards, 12th of 48; at 102 mph its carry fell to 44th. Judge it on flight and spin, not a speed cutoff.
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 Global’s Vietnam plant — 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.
Is the Kirkland Signature Performance+ good in cold weather?
Not especially. At 95 compression it is already firm and low-launching, and cold air makes both worse, so a softer ball is the better winter pick.
How much does the Kirkland Signature Performance+ cost?
About $15 a dozen at the Costco warehouse ($29.99 per 2-dozen box). Costco.com lists the same box at $39.99 shipped.
