First post... longtime fan.
I’m living in Australia, and I’d like my parents to bring me a couple Tom Bihn items when they come to visit soon. I had a Brain Bag shipped here recently, and I want to try using some packing cubes with it. I read on some other threads that some use large aeronaut packing cube shoulder bags and packing cube backpacks with the brain bag.
Question is: do they take up any room when empty? (my parents want to know since they’re bringing them to me.)
