Nice quality, but with a downside
Really nice quality. Usually with this kind of material, I would be afraid to rip it, but definitely not with this one. Furthermore, it is very well thought out, and even gives you an extra small compartment.
However, I'm a bit sad that the shoulder straps aren't longer. I'm a quite big guy at 194cm (6.36 ft), and it kinda feels like the bag is sitting a bit high on my back, even with the straps at their longest. I've tried other stuff packs of the same type, which was much more comfortable for me to wear, because the straps were longer.
Overall, this is a great buy if you aren't as tall as me.
