I have been using this everyday as a commuter backpack for about 6 months. The quality is very good. The straps are excellent - padded and not painful. They don't loosen and stay in place. Side pockets are great for holding pepper spray/umbrella. Design is sleek and modern.
However, the material is very rigid - it maintains the structure and keeps the bag sturdy but it makes for a bulky commuter backpack. Was hoping it would soften a little over time but it has remained pretty rigid - this could be a pro for some people. The bag is not lightweight but I believe it's because of the sturdy material. Diameter is also thin so does not fit lunch properly. I wish the inner pocket was placed higher up inside the bag so it would not take up so much space towards the bottom of the backpack where I wish I could fit my lunch. The inner pocket is placed directly behind the front outside pocket so if you have items in both sides it gets bulky.
Overall great quality backpack, just wish it was less rigid/bulky and also wider in diameter!
