Up to about 8 months ago I was unfamiliar with Tom Bihn products. When I found the website I easily got sucked in. I travel a good amount for work and I found a number of great solutions to business and personal travel issues. I started with a Tri-star then added cubes and pouches. Got a MCB for the weekends and then a Zephyr for daily work use and eventually another MCB for my spouse and I loved all of them. Finally, in a moment of Tom Bihn obsession I also picked up the co-pilot.
For some reason I just could not find a great use for it. With the Tri-Star my stuff was already relatively close at hand in the overhead. The MCB was more comfortable to wear around town. It took a big adjustment on my part to get used to one bagging it so two bags seemed like I was moving backwards. However, I have to say the co-pilot really shines for me as a light travel briefcase at conferences. I do not need my laptop during the day so I can leave it in the room (or in the Tri-Star). The co-pilot holds files, materials, pens, notebook, iPad, phones, etc. to get you through the day. Mine is black so it looks more professional vs. my MCB as well.
I also didn't realize when I bought it how well it fits in the front of the Tri-Star while still leaving room for shoes. This allows me to one bag it through the security and ground transportation stages but travel light when I get to my conferences. I guess my Co-Pilot was a solution waiting for a problem for a while but I am glad I have it! I have not found a great use for the water bottle pocket on the Co-pilot or the Tri-Star yet but maybe that will happen someday too.
