Bearing in mind I only had it a couple of days...
I don't like the lid arrangement, when it's not so full you can't tighten it properly (buckles on the front are too high).
Lid pocket too small.
I'm sure on mine the hip belt was not removable (AX40).
Needs a way of storing the rope compressor better.
It was super comfy though and a good shape. I like that the cord for closure is suitable for rapping off, I thought the weight was good for the size.
There's probably a few other things I thought were good and not so good but I can't remember. I think it's a really good bag, just not for me.
With their streamlined designs and durable fabrics, crux rucksacks are renowned for being lightweight and tough. The new AX rucksacks are no exception.
