This has proven to be a very durable bag. After daily use for about a year for trips to/from preschool as well as travel by car and in airplanes, it has held up very well, with hardly any visible signs of use (despite the usual treatment from a 4-year-old boy). The colors have also stayed bright and vivid, pretty much just like they were when we first bought it.  Also, the zippers are excellent -- very easy for little hands to work, yet strong and not easily jammed up. Would definitely buy it again.
