My wife bought me this bag about 10 years ago (maybe 15... we're struggling to remember because it's been so long!).  I have used it as a gym bag 5 days a week all of these years.  I've also used it on over-night or 2-day business trips.  Last week I finally had my first issue - the end of the zipper fabric in the top tiny side pocket lost it's stitching and the zipper came off when I went to close it.  That's not bad for 10-15 years!  I came into Amazon to see how much they cost now.  Sadly, I see they only come in black (I also checked the manufacturer's website... where the cost is about 50% more than Amazon).  I like the blue of my old one so I'll just stitch up the zipper.

This bag is not made to carry text books.  If you're looking for a book bag, look for one shaped like a book.  This bag is an awesome gym bag or an overnight bag.  The bottom section fits shoes (I wear a size 11) so they don't get your clothes dirty.  There are several zippered outer pockets and several pockets inside (one zippered, if I remember right).  I fit all of my lifting gear with no problem, including my shoes, belt, towel, and water bottle.  I can carry enough clothes for a 2-day business trip, including my small mountain of bathroom stuffs.

In short, this is one of the best bags going (I think it used to be the manufacturer's bread-and-butter).  I just wish it would come in color options again.  The manufacturer should take a lesson from High Sierra on that one.
