Product Review (submitted on August 5, 2008):
I bought this bag back in 97 and used it for my years in grad school and after until 03. During this time I rode bike to work every day rain snow or shine. I overstuffed it with heavy books time and again. I used it to run errands all over town. When I cleaned up, I used it for travel to conferences and presentations, and for a few years after.
After several years, some of the trim started fraying from use. I sent it back and DP replaced the trim. At this point I still have and occasionally use my pack, but use something larger to go to work nowadays.
Since I used mine for bike commuting for years, the 4 stars reflect DP not having a few things that specifically bike-oriented bags will include. First, someplace to hang a rear blinkie would be nice. Second, a little more volume would make it easier to pack a t-shirt on sweaty days.
OTOH, I don't think I have any bags that put up with such heavy duty daily use as this one, that are still going strong.
