The X-SB is a 27.5" quick setup, 18 bone softbox. It simply clicks into place allowing users to setup in seconds. Included are 2 layers of diffusion (inner layer and outer layer) as well as a 40 degree fabric honeycomb grid to control light spill. Also included is a carrying case.
The X-SB uses a Bowens-S Mount meaning it can work on the X-100 or any other product that uses a Bowens-S Mount.
