A great bag to take on an airplane, especially when I'm not getting any checked luggage. First impression of the bag is that it is quite well built and sturdy, it has some weight to it but it's still quite light. The zippers are big which is handy and you can hide the backpack straps easily. The entire front of the bag can open which is pretty cool.
I'll post an update once I pack and then once more at the end of trip. The only worry is that once I add things, how the straps fare when they're on my shoulders for hours.
I also bought the little compartments to pack things in and those seem to have the same build quality as the backpack which is a good sign. Not sure if they will be useful.
