No guaranties, but I've used a soft-sided (canvas) Stahl Sac for years without any issues. I wrap my Reg setup in a big beach towel, wrapped around it like a burrito, then stuff that inside my BC, which I them tie up tight with the belts, then wrap up with my Fleece-lined Henderson. I make certain that the BC-Reg package is buffered by other soft or flexible stuff -- Fins, Booties, T-Shirts, etc. masks (I usually pack 2-3) I wrap in clothing or in the plastic cases they came in. Never had any breakage or losses. I don't carry any big photography equipment - my small digital Intova goes in my carry on. If you've got large expensive photography equipment, for that I would probably use the foam-lined hard case.
