Hey Stan
The thing that struck me about these cases is that they are as tough as old boots...you really could use them all the time.
The locks are quality, the construction sturdy, you almost could imagine them getting thrown around on an airport conveyor, that kind of thing.
It must be the MB Tex they are made of. They were designed to be chucked in the boot (trunk)
I had imagined ,from the few pictures available online, that they would be flimsy things but its not like that.
I dont, however, intend to do any of these things, but it is worth mentioning that the cases could take it .

(i wont be putting my mucky socks in them, dont think they could take that)
