I love backpacks, and having something really comfortable and light is key for hiking. I wouldn't use my MZW/Tumi for hiking, it would get all sweaty. My DD has a Kanken and I would not consider it comfortable, although cute. I like to have a good spot for a water bottle or hydration system.

That Knomo is super cute though and I would love something like that for general travel - it looks like the Tumi Voyageur but like half the price! But no water bottle pockets is a no in my book - looks like you have to stuff it in the main compartment.

I have an Osprey that I love for hiking, it is really nicely ergonomic. Something like this, but a different color.

This one is super boring but I use it for everyday, it has really good organization, and great for work travel too.
