We've owned the CP messenger bag and most of my daughter's friends have owned the backpacks (one year our carpool had three of the same pattern- which was challenging until the girls got into hanging keychains off of them and made them more distinguishable). I feel they have held up well. My daughter is only going in to 4th grade now, so she hasn't had to carry a huge load of books around at a time. I don't know how the bags would fare under those circumstances. If you have an older child, who will be stuffing it with a heavy load, I'll share that I bought my L.L. Bean backpack in '87 0r '88, schleped it through high school, college, here, there and everywhere as a mom, including Disney, and it's still in great condition. Good luck!
