Beware there are different types of Samsonites.
The 'oyster' clamshell where the two halves overlap at the join are brilliant and keep out dust and moisture.
I have never been in a position where one is submerged thankfully, but African dust is pervasive and the oyster keeps it out.
But at risk of repetition, not all Samsonites have oyster closures. Look for hard fiberglass i(US spelling!) with interlocking closures. They are brilliant.
