Costco's Kirkland Signature golf balls appear to be on their way back to Costco shelves, perhaps sooner than later.
Two Kirkland Signature golf balls appear on the latest version of the USGA and R&A's list of conforming golf balls as of March 1.
One is the Tour Performance marking and is a 360-dimple, four-piece ball with a solid core an a seemingly unheard-of triple cover. It seems to be the original Costco Kirkland Signature Four-Piece Urethane Golf Ball, sold for $30 for two dozen balls and made by Nassau Golf Co. Ltd. of South Korea. It's still conforming, so it should still be on the list.
The new ball is the Performance One Kirkland Signature ball. It also has four pieces and has a triple cover, but not a solid core. These balls are rated for medium to high spin and are made by SM Global LLC, an American subsidiary of a Korean company that is the new manufacturing partner for Costco.
Of course, we don't know when these balls will be for sale, and we don't know how much they'll cost.
