Triple-Deck Specs

They can also be unlocked through leveling up the Drizzle Season 2023 Catalog to level 100.

Appearance
The Triple-Deck Specs consist of three separate pairs of glasses of different styles: the uppermost pair has square lenses, has a tortoiseshell pattern and is larger than the rest. The middle pair is rounded and has a single lens that stretches across both sides and is wider at the center. The bottom pair is similar to the middle pair, except the frame is thicker and the lens narrows at the center. The bottom pair is the pair the goes over the wearers eyes, the other two simply rest on the players forehead.

Trivia

 * The Triple-Deck Specs's primary Ability (Sub Power Up) matches the favored Ability of its brand (Enperry). This is likely a developer oversight; the series as a rule avoids these combinations to make achieving maximum AP more difficult.
 * The only other gear to have this distinction are the Retro BluFocals from Splatoon 3, as well as six items unintentionally sold on SplatNet 2 with matching Abilities; see that page for more details.
