Here's another option for packing cubes and I like the looks of these.
The Seattle-based Tom Bihn company is mostly known for its fantastic travel bags. Rugged and Made in the USA, they inspire fanatic devotion. I'm about to become a devotee myself I think. I'll be trying out their Aeronaut carry-on bag for a four-night trip next week and am actually looking forward to packing.
The company also makes loads of neat travel accessories though, including a wide array of packing cubes and gadget bags. I have mixed feelings about the necessity of these organizers, but my post on the Eagle Creek packing cubes before remains one of the most popular posts on this blog, so obviously people like the idea of getting their undies organized.
There's only so much innovation and differentiation you can put into little pouches that zip close and fit into a suitcase, so Tom Bihn's packing cubes mostly stand apart on style and color. They all have a checked pattern and come in either Steel (dark gray and subdued) or Solar (bright yellow). They have good YKK zippers and ripstock nylon fabric. They're mesh on one side so damp clothes don't build up mildew. Here's the real difference though: they're not made in China. If you want to put your own personal stimulus plan in place and buy American, you can do so at Tom Bihn without paying a premium. The cubes are $15 to $18 each and should last a decade or two.
The company also makes a 2-sided clear packing cube that is great when you want to be able to see exactly what's inside or you've got liquids you're afraid could leak onto everything else through mesh. In theory this should work for carrying cosmetics through the security gauntlet at the airport, but it depends on the mood of that day's TSA agent: carry a spare plastic bag in case.
