I'm a big fan of packing cubes. I have a full line of Eagle Creek and the old RS ones.
I've gone back to using the RS convertible and with the sale going on thought I'd upgrade to the new RS cubes especially since they state they fit perfectly inside the bag.
The bag is 21 x 14 x 9. The cubes came today. One is 11-14. The other two are 11 x 7 3/4 each. That means with all three put together it would be 22 x 15.
They are an inch longer in each direction than the bag. With the 'sturdiness" of the cubes, it's harder to get them in than the old cubes.
For those of you that have the new cubes, do you really get them to fit?
