The DJI Phantom 4 is a great drone and comes with a case that looks like a steak cooler of sorts. The included case is not even remotely ruggedized or waterproof. This DJI Phantom 4 case is super heavy-duty. TSA locks can even be attached for travel. It has a pull-out handle and wheels! It’s not too large in my opinion to be manageable. Although I don’t recommend it, I have swam with this case and it did not leak!
