It's an Oakley Kitchen Sink. I bought it for work travel mainly, but the thing is a beast. Not for everyone, of course, but if you can find a place that sells one, I highly recommend going and checking it out. Some of the things I like:
- ample size in the top "hard shell" compartment which is lined with material to keep glasses safe from scratching
- removable waist strap system for days when you don't need it
- waist strap comes with pockets as well
- those beefy intimidating clips holding the top down are SUPER easy to take off and put back on (you pull on the bottom and it forces itself off the hook)
- full side zipper for easy access to laptops (my 15" macbook pro slides in and out with ease)
- huge main compartment
- main compartment has a ton of extra material on the bottom. there is a zipper on the bottom of the bag for access to a place for wet items - the extra material is to make room for that stuff on the bottom
- huge front pocket (you can see the two zippers for it hanging near the metal hooks in the front. has tons of mini-pockets and velcro to keep stuff from flying around.
- side pockets are huge, but can be tightened down
- i do a lot of rock climbing, so the metal hooks for carabiners, as well as hanging other items is a huge plus
- super comfortable on the shoulders, and nice balance for distributed weight
You'll pay a pretty penny for it, though
