Following its bag drop last week at the Children’s Aid Society in Harlem, State Bags announced that it will donate 30,000 backpacks filled with school supplies to children in need as part of President Obama and the U.S. Department of Education’s My Brother’s Keeper Success Mentors Initiative. State Bags, a buy one, give one Brooklyn-based benefit corporation, is partnering with Roc Nation for the effort, which will stop at cities nationwide, beginning with New York on Aug. 9 when participants will include Angie Martinez, Cipha Sounds, Santigold and Justine Skye.

After that, a bag drop on Aug. 29 in Los Angeles will feature Big Sean and DJ Mustard, writer Joelle James and artist Casey Veggies. A Sept. 7 bag drop in Dallas will include WNBA All-Star and Dallas Wings forward Skylar Diggins. Additional dates will be confirmed in Detroit, Miami and Baltimore, State Bags said.

“Roc Nation is proud to collaborate with State Bags,” said Dania Diaz, national director of philanthropy at Roc Nation. “They provide essential materials to succeed in school, including mentors, encouragement and motivation for students in need. Along with State Bags, Roc Nation’s family of artists and athletes hopes to inspire and make a difference on a national level by connecting in a local and intimate way.”

“This partnership with Roc Nation will not only provide a tremendous platform to equip thousands of students across the U.S. with the proper tools for success, it will go beyond simply a material donation through our motivational bag drop donation events in select cities,” said Jacqueline Tatelman, State Bags cofounder and creative director.
