The Eagle Creek Specter cube series seems to be just what I am looking for. Still a packing cube design for easy access, but non-mesh for liquid protection. On top of that, it is translucent to allow cursory inventorying, and is supposed to be especially light. I'll let you all know how my purchase fares.

What you seem to need are waterresistant rolling bags like that. Ortlieb is a well-known brand name, but also a bit expensive. If you look out in outdoor stores or motorbike stores (they have often inexpensive bags which are used to store things which should not get wet), you should be able to get an inexpensive brand.
