Nice fabric, strong but lightweight.  Good color choices.  First trip out one of the strings frayed on the side pouch.  Pouches seem too big to securely hold a bottle of water so I probably had it cinched pretty tight.  By the second trip using it, the black handle strap at top was coming off on one side and the stitching was coming out on top of the middle pocket.  It fits me fine but would never fit my hubby.  I'd say get a sturdy Jansport or Eastpack instead.
