Arna

The Arna name has run across three releases on record: the original Arna, the Arna (Sigma 2), and the PING Vault Arna. Australian Golf Digest's coverage of the base Arna described it as carrying moderate toe hang, a trait that points to a face-balanced-leaning design suited to a certain stroke type, though that characterization comes from the publication and not from Ping itself. The name's continuity across three separate releases suggests Ping found something worth returning to in the Arna shape rather than treating it as a one-off.

By the time of the Arna (Sigma 2), Plugged In Golf's reporting described the head as a traditional mallet, which tells us something about how the line's silhouette was read by outside eyes at that stage, even if the line's earlier toe hang characteristic wasn't necessarily reconfirmed there.

The PING Vault Arna marks the line's move into Ping's Vault tier, and it's here that the most detail survives in our files, all of it from Plugged In Golf's reporting rather than Ping's own materials. That coverage described a midsize option finished in Platinum and Slate, fully milled, fitted with a True-Roll face, recommended for a Slight Arc stroke, and carrying a reported 300 USD price. None of those figures are verified beyond that single outlet's account, but taken together they sketch a Vault release aimed at the premium end of the line, a step up in construction and finish from what the Arna name had carried before.

Across its three entries, the Arna line reads as a name Ping kept reworking rather than retiring after a single release, moving from a base version through a Sigma 2 update and finally into the Vault tier's fully milled treatment.
