Hand luggage format, it takes the plane with all its equipment, which will be fully protected ... A reflex or 2, 4 goals, chargers ... it's perfect for taking all! The modular bay is excellent too. The port is very nice but it's full it's pretty heavy ... the Rain and dust protection is very effective (I live in Dubai and travel a lot), even if it prevents to take the tripod if installed. In short, the serious hardware, well thought out and very practical!
