This is my fourth Pelican. They're what I use mostly for camping, but they're also great when traveling by air. Unlike soft side luggage which can be crushed, there are no zippers that can be popped by the growing trend of thieving baggage handlers. There's a video up on YouTube showing how zippers can be opened and closed so you won't even know you've been robbed until you get to your destination. I was pleasantly surprised when, at the end of the video, they recommended something I've already been using - these cases. I won't say I abuse 'em, but they've all handled being loaded with camping gear, and bounced around in the back of the pickup while driving around the unpaved back roads of the huge State Parks. The wheels and handles aren't of much use on dirt while camping, but they're excellent for running through airports.
