First off, the positives.
The backpack looks great, clean lines, the perfect shade of green that I wanted. Really stylish looking compared to my previous backpack that was very much a hikers pack.
The full length zip access took a little getting used to but had actually turned out to be incredibly useful. Not sure I'll be able to go back to a standard opening.
The build quality and material feels like it will last a good while and I particularly like the lining of the main pockets.
Cons.
More internal pockets please! The laptop/folder pockets are fine but the other one doesn't really work properly for my use case. If you put pens in the internal pocket you can't zip it up, and the material on that pocket specifically has me worried that it will tear if I put to much stuff in it.
More seriously, there are some patches of yellowing on the outside underneath where the flap folds over. I haven't had any spillages or splashes of anything that I'm aware of and it's not in a place that is accessible when I'm wearing it so I have no idea what's caused it. I don't know if it's a defect that I didn't spot or if it's been affected by something I've put in my bag (can't think what though). Will keep an eye on it.
