Unbelievable quality, it holds countless things, it's like having a small suitcase on your back. I've had it for over 3 years and it still hasn't suffered any damage.

Very good bag.. spacious and with dual use. Both for everyday use and for travel as it can be used as a suitcase for moving to Australia (!) and opens up completely for placement..
Every day at work where I use it, the 33L can easily fit 3 food containers, a laptop of 15.6 inches (slightly smaller comfortably), chargers, cables, notebooks. It doesn't have as many compartments (4) as others but you can really play Tetris and fit a lot of things inside.. 44L is better for travel, and the small one (28L I think) exclusively for commuting to and from work. The color, out of all, is personally my favorite. Neither a variation nor a simple black laptop bag that you find everywhere..
The only negative is that it doesn't have the cushion on the back to keep it straight, and you either have to put notebooks or books to keep the back straight manually.
