A two-day exhibition recognizing American-made clothing, accessories, food and music will be held in September at the Innovation and Design Building in the South Boston Marine Industrial Park.

American Field will be held on Sept. 13 and 14, and will feature more than 100 U.S.-based manufacturers. The event will include live music, a beer garden and food from local restaurants and food trucks.

The festival, now in its third year, highlights the economic benefits of buying American products with demonstrations, workshops and lectures.

Atlanta-based Jamestown acquired the 1.4 million-square-foot Innovation and Design Building last year and announced plans for a $100 million, three-year renovation of the complex. It’s sponsoring this year’s festival along with Boston-based clothing retailer Ball and Buck.
