The 48 x 48" Matthews Matthbounce Floppy is a popular size that can be transported in a van or grip truck. It features a black exterior, but once you undo the touch fasteners at the corners, the Matthbounce flops open to a large white reflector that allows a nice return and soft quality of light. The frame is made of hollow steel tubing to cut down on weight, while the solid steel mounting rod can stand up to years of heavy use.
