It was easy going through airport security, just unzipped and laid the backpack flat with electronics on one side and everything else on the other.
I can't believe how much stuff you can fit into it yet still get the slim look, due to it's design.
I'm used to carrying heavy objects but between the padding and the way the shoulder straps are constructed I barely feel the weight of anything.
It fit under the seat in front of me on the plane and I had it packed to capacity. The shoulder straps are incredibly comfortable.
