For the fourth year in a row, Major League Baseball is rolling out its creative, yet polarizing, City Connect alternate uniforms.

The special series was introduced in 2021 to shine light on the history and culture of teams and the cities they represent. They've also become a hot-button topic with fans, who either adore the designs that are unique to their favorite team or find them absolutely appalling.

MLB also announced that its Nike Vapor Premier jerseys will be part of every uniform this season, including the City Connect threads. The jerseys, which were first introduced at last year's All-Star Game in Seattle, are designed to improve mobility, moisture, management and fit.

Here's what you should know about MLB's City Connect uniforms:

When will MLB teams reveal City Connect jerseys?

This is still yet to be decided, though MLB announced it will come between opening day and the All-Star break.

Does every MLB team have a City Connect jersey?

No, but after this season there will only be two teams left without one: the New York Yankees and Oakland Athletics.

One could surmise the reason the A's are being left out in the cold is their pending move to Las Vegas. Meanwhile, the Yankees have been rumored to remain on the sideline for this promotion in favor of staying in their vintage pinstripes. Team owner Hal Steinbrenner addressed that on "The Michael Kay Show" in 2023.

"I'm not having any conversations about doing it," Steinbrenner said. "I think I understand the reason − and again, I think it appeals to a lot of fans, especially younger fans, and you know, merchandise and all that. But we have not had any serious conversations about doing it. It doesn't mean I won't someday, but I don't even know how that would look, quite frankly. I don't even know what the look would be."
