"Nice size but not tall enough for one liter MSR fuel bottles"

Why would you put these in a dry box?  I leave them outside the plastic liner in my pack and put them in the bottom because I don't care if they get wet.

The whole liner and water proof issue surprises me.  I've never used more than a pack and plastic liner - the heavy clear vinyl ones outfitters often supply - and never ahd a problem - including a dump in white caps in October - 40 minutes from shore.  (My lack of wearing pfd  was clearly partially offset by the very bouyant packs.)  Everything inside was bone dry.
