Online Jersey

Appearance
The Online Jersey is a gray jersey with a blue-and-white trim on the sleeves worn over a dark red long-sleeved shirt. On the front is the Japanese text オンライン (Onrain, literally "online") in blue. The right sleeve has a patch with the Nintendo Switch Online logo near the shoulder. The logo is printed on the left sleeve.

Trivia

 * The Online Jersey's baseball uniform aesthetic pays homage to the annual Splatoon 2 Japanese Koshien tournament and is based off similar baseball themed designs often found in promotional artwork for the event.
 * Similar real-life versions of these outfits were also worn by Japanese team and Koshien veterans, the GG Boyz, during the Splatoon 2 World Championships held at E3 2018. The GG Boyz's uniforms had the Splatoon Koshien 2018 logo on the right sleeve (presumably covered up by the Nintendo Switch Online patch).
