LowePro Computer Trek Plus is a great bag and will safely hold ALOT of gear. The quality of the construction is top notch, stitching, zippers, fabrics, buckles. Great for air travel as you can always have the gear with you in the overhead. Drag this bag all over asia, the south pacific, north america and europe, not a tear or one broken part yet.
Additionally the design is well thought out, inside thickly padded areas with adjustments, load levelers on the shoulder straps, nicely padded waste belt, many pockets for your photo support gear. A rain cover that neatly hides on the bottom. If you are familar with lowePro the have "slip lock" add on pouches, and the side of the pack have slip lock loops, so you can add on additional lens cases, phone cases, pda etc, which are very handy.
The outside layer of the back contains a special pocket and straps for your tripod. Inside that first layer is a large pocket sectioned out for you office related gear, pencil, paper, manuals, memory cards. Next Layer opens into the main padded & adjustable compartment for 5 lenses, Flash, 2 dslrs and some other accesories fit nicely. One more layer down is a side open padded pocket which the laptop will slide in. This bag is also airline carryon and will fit in the overhead fine. I was stopped once only while security measured my tripod and approved its length.
Two complaints ; with this pack loaded it is VERY heavy, something I did not think about. Also - there is no way to safely stowe the bag on top of a rolling luggage piece while walking through the airport. Even with the above complaints I could not imagine travelling with out the CompTrekPlus. Recommend checking out the "Pro Roller Series".
For walking around I also travel with the "400reporter" and the "Offtrail2". I hate to keep buying bags but you just can't have one bag. At the moment really interested in the 7million or 6million since this bag is very inconspicious (non-camera looking).
Just noticed MORE slip lock loops on the waist belt.<<<<<<
