I'd been looking for a medium-sized everyday bag to take with me on my commute and thought I'd found it in the Superbad Backpack. Unfortunately, the bag is a little bit big for me to use daily (and you might want more organizing-type pockets), but I looove using it for travel for a long weekend. I recently brought it with me for a 4 day trip and was able to fit enough clothing for all four days (2 pairs of pants + 5 shirts + 2 pairs of shoes + toiletries) with some room to spare. This bag fits easily underneath the airline seat and also in the overhead compartment. The rectangular shape also works really well for a trip to the grocery store and doesn't tip over when it's upright. This bag also doesn't make me feel like I'm wearing sort of a boxy "astronaut-like" pack, either.
The straps are comfortable for my frame (mid-sized female). The ballistic nylon is sturdy and the zippers, while smaller than I'd thought they'd be on a T2 bag, easily slide. I also like that the main zippers don't go all the way down the sides of the bag (much easier to stuff a lof of gear in there as well!). There is a laptop compartment in the back, which is accessible from a zipper on the side and from within the bag. I haven't used it yet for my laptop, but was able to put some magazines and newspapers in that compartment for the trip.
I look forward to using this pack on my next trip.
The name is a bit misleading because I'd call it "Supergood"! :-)
