Pelican cases are fantastic and have been the "duck's nuts" for quite some time. You might also like to check out Storm Cases. There were an independent company but were bought out by Pelican last year some time by the looks of things. They are essentially the same material with a different latch. I find the latch on the Storm Cases are a bit better as the Pelican latches can get really hard to open after a harsh life.


I work in an underground mine and I'm also in the Mines Rescue squad so you can imagine what sort of environment we work in and how roughly the cases are treated. Both the Pelican and Storm cases have been flawless.


I've had my 40D and a couple of lenses in a Pelican 1510 while kayaking through white water and the tetherto the case broke (not the fault of the case, the rope I used snapped when the case went overboardand got caught up on a log). Foundit about 6 hours later still wrapped around the same log and not a drop of water got in. Made me rather happy.


Both the Pelicans and Storms have a pressure relief valve that adjusts depending on altitude. This is handy to equalise the case otherwise if the pressure inside the case drops for some reason it'd be near impossible to open.
