About eight months ago I received my Tri-Star and am currently using it for a business trip (to Moscow of all places - minus 16 degrees celcius right now).
Packed for two nights, it contains a suit; two shirts; ties; change of underwear and socks; a 3D clear organizer cube with shaver, tooth brush, etc.; a 14" ThinkPad with charger; a presenter; a book (The Holmes Affair by Graham Moore - halfway in and can strongly recommend it); iPhone charger; keys and the cord zipper pulls that came with the bag that I've been meaning to install ever since.
It stilll have plenty of available space if I wanted to bring an additional book or more clothing (could probably have fitted the gym clothes I really should have brought).
During the last eight month I've been using it on countless trips and have always found it easy to pack, easy to find what I need while on the road and (important for a bag that is not a trolley) easy to carry with the Absolute Shoulder Strap no matter how full it is. Also, it still looks pretty much like the day I got it.
As always a great product from Tom Bihn (this is my third bag) and strongly recommended.
P.S If you are wondering how good the Absolutely Shoulder Strap is: I once forgot my laptop at our local office in Baltics and didn't discover it until I had to take it out for airport security - there really wasn't that much of a weight difference!
