I recently received my first Tom Bihn bag, a Black/Solar Aeronaut. I was so impressed by the design and quality that I purchased a second one for my wife (Crimson/Steel) as well as some packing cubes and pouches. Being a Steeler's fan, I also love the Black/Solar color combination. Now I am in need of a good +1 personal item. We try not to check bags anymore so I would like a good option that can be carried with my Aeronaut on longer trips. I just ordered a Brain Bag but also considered getting either a Tri-Star or Western Flyer. I like the idea of carrying the Brain Bag because I can use it as my daily bag to carry around at our destination, but I don't know if it would pass as a personal item. Plus I would prefer to wear the Aeronaut as a backpack and carry my personal item over my shoulder. I considered the Checkpoint Flyer, but at 950 cu in, it is a bit too small. I usually carry a 15" Macbook Pro, a Nikon D200 with a few lenses, some binders, manuals, e-reader, and some odds and ends. Does anyone have any experience traveling with an Aeronaut plus any of the options I am considering as a personal item? Any input would be appreciated.
