Any good recommendations for a backpack I can use in College?

I'm looking for a new backpack and I kinda want something cool/fashionable but not flamboyant. I also want good quality. I like North Face backpacks but they're pretty popular and I kinda want something unique lol. I'm open to any advice tho!

Edite: Wow thanks everyone for your feedback! This really helps! I really like that Carryology website, so thanks straightc! And thanks everyone in general. I'm gonna go through these sites and check out all the things!
