Sprayground, the urban backpack, clothing and accessories brand, will open a quickie pop-up shop later this month dubbed, “Seven Days of Mayhem,” at 140 W. 42 St., near Seventh Ave.

Founded by David Ben-David to create the “rebel of all bag companies,” the company melds edgy artwork and functionality. Its cult followers and Instagram users ensure its collectible collections get global attention in minutes.

The 5,300 square-foot first floor pre-holiday attention grabber will serve cocoa and expects its shoppers to chill and post photos as they take advantage of the Times Square area’s long shopping hours. Open from noon to midnight each day, the store kicks opened on Sunday, Nov. 19 and runs each day through Sun. Nov. 26 — except for Sat. Nov. 25.

The new collection includes a collaboration focusing on Muhammad Ali and a boxing ring setup will help launch the designs.

The Newmark Knight Frank Retail team leasing the space at the base of the new Hilton Garden Inn is led by Jeffrey Roseman along with Marc Lieber and Drew Weiss.

The entire 17,000 square feet on four levels is available with an asking rent of $400 per square foot based on the ground floor rent, and has a huge, marquee style LED screen to ensure visibility.
