I recently made a new discovery which I intend to use.
Amazon has some very big bags with zippers made by Ikea of their blue fiberglass-like plasticy material which is pretty much indestructible. You could probably get most of a summer wardrobe in two of these bags. They're inexpensive, have web handles and can be pressed into different odd spaces. They'd be water, dust and insect proof. They could just be thrown in the bottom of a closet.
These would also be great for moving.
