Porta-Brace has some nice hard cases (suitcase style). I have a large one (PB-2700) that I use when I'm in the back country shooting from my 4WD. It's nicely dust-proof, has a foam interior, etc.
I also have an f-stop Loka that I take on similar trips when I've got to pack the gear as well as keep in handy in the car. The Porta-Brace is great for getting to the gear quickly. Loka not so much.
I pack a D810, 70-200 f/2.8, 300 f/4, 14-24 f/2.8, the 105 f/2.8 and a TC20. I can't get it all in the Loka but it easily fits in the Porta-Brace.
I also have a Think Tank Urban Disguise 60, which can handle the D810, the 14-24 and one of the teles. It's a nice case, good for crowds, because it looks like an ordinary messenger bag. Doesn't attract attention. Neither does the Loka, which looks like a high-quality back pack but reveals nothing about what's inside.
Nothing against Pelican -- I've had plenty of them for other tasks. I prefer the Porta-Brace look to the Pelican look.
