I can very much endorse the Peak Design Packing cubes. I'm surprised they are so high quality and so well made - inside out. Stylish too. Far better quality than the LVMH garbage Alesandre, later Hugues put out. The only thing the current Rimowa CEO did that I like was the lifetime warranty. Now if they could only bring back the center lock and the bag holder.

Peak Design has boutiques in San Francisco and New York, naturally. You won't find anything so well made in Europe. Check them out for yourself.

Specifically I use 1 medium and 2 small for the cabin, and I also use this for the top compartment of the Trunk.

I ended up getting a bunch of stuff from their store. Several cubes. The bags are great too - esp if you own cameras. Recommend enthusiastically. A little high ( more than eagle creek/ away) on the price but compared the LVMH garage cubes from Rimowa, a bargain and far better quality / make.

Have you seen what Rimowa wants for a stupid luggage belt? Play with ones vanity it will lead to insanity I always say.
