With enough space for two GoPro HERO4 action cameras (without housings), you can bring the FPV Action Camera Pouch from Think Tank Photo with you on your adventures and be ready for impromptu video capture. The case itself has two zippered compartments. One holds the cameras and the other has pouches for the batteries and a separate zippered pouch for extra memory cards. The main compartments are lined with soft material to protect your cameras' finish.
