I've had this bag for about 9 months. I have the black/red medium and use it for my daily work and occasional travel carry on. It mostly contains just my 15" laptop, blue tooth mouse, work phone and other small items. I keep the laptop in the large center portion not the sleeve. For my usage it's been absolutely fantastic. It still doesn't show any wear and the couple of times I've really packed it full it's still been great. I've had to dust dirt off it once or twice, but the black hasn't ever stained and it still looks as good as the day I got it.
