Urban Air Market has been going strong in San Francisco for a decade, where it goes down several times a year in neighborhoods like Hayes Valley and the Lower Haight, and this summer—August 2 & 3—it's making its debut in Portland. Its emphasis is on the sale of sustainably produced goods, bolstered by additional attractions like live music and beer gardens, and it'll be the first real event to warm up the pastures of Zidell Yards. Another way it plans to differentiate from an increasingly busy market of pop-ups and fleas come from its Bay Area connections, with SF vendors mingling among like-minded Portlanders (collaborations, anyone?), adding up to a day of sunny outdoor shopping and entertainment for you (entrance is free), without the tie to winter holidays that bungles up so many budgets around these types of large-scale shopping events.

Though the Market has partnered with a variety of local entities to some extent (including, recently, ADX, Portland Made, and Know Your City), the list of vendors is still being finalized, and you can still apply to get your foot in the door.
