The Go Professional original series XB - 552 Case for Gopro Cameras and accessories has not one, but two specific cavities for the GoPro cameras! The XB - 552 case has two layers of customized cavities made of rigid foam, so it will last longer and maintain its shape. The top layer will hold 2 GoPro HD2 cameras, cords, battery packs and other GoPro stuff and the bottom layer of foam is a large cavity for suction cups, headgear and general storage.
