Trying to find a one-bag solution to backpacking through Europe/Asia. I currently own an Aeronaut and a Synapse. Great bags by themselves but I found that they are unwieldy when carrying them together. Also, I was concerned that some overseas carriers have smaller carryon limitations. I was looking at the Brain Bag for extended backpacking travel. Inside I would carry a single large Aeronaut Packing Cube for clothing and the new Pilot with accessories. In this manner, I could easily pull out the Pilot as a daypack. I would probably carry an iPAD, water bottle, GPS, camera, guidebook, snacks, and some assorted sundries. For those of you with the Brain Bag and/or Pilot, would this setup work?
