Like the title?  There is basically no way I can make packing cubes seem interesting, but some shit is necessarily boring.  The truth is, I love my packing cubes.  There, I said it.  They make me feel safe, comfortable, and superior to everyone with a disorganized bag.  If you’re anal, organized, or just don’t like unpacking and re-packing everything in your bag just to get a pair of fresh undies then you should buy a set of packing cubes.  Pretty much everything in my bag is organized into 4 cubes:

this 3 pack:  Rick Steves Packing Cube Set, which hold all my clothes, 

and this one: eBags Medium Packing Cubes – 3pc Set

(we bought the 3-pack, each used one and had one leftover).  I use the eBags for heavier things like power cords, outlet adapters, ect.

So far they all work great, no problems with the zips, and my bag is nice and organized.
