The event, first organized in 2002 by performance group Improv Everywhere, featured hundreds of people riding commuter trains in their underwear Sunday in cities including Chicago, Boston, Berlin, Calgary, Dallas, Mexico City, Tokyo, London, Lisbon, Los Angeles, St. Peterburg, Melbourne and San Francisco.
The flagship event in New York, which was the site of the first No Pants Subway Ride, featured more than 200 people alone. Organizers said this year’s ride was bolstered by unseasonably warm temperatures, which reached the high 60s Sunday.
In Chicago, where about 175 people without pants boarded the trains Sunday, participants braved more balmy conditions, with a high of 32 degrees.
“Thanks to everyone who came out to participate in this year’s ride,” Improv Everywhere said on its website following the event.
