Laptop bags are generally nerdy-looking awkward and inelegant things that you wouldn't want to be seen carrying around, but this perhaps somewhat overpriced $99-backpack from Razer seems like an exception to the rule and looks pretty neat to me:

Smaller and larger sizes are also available, for different size laptops. Check it out if you're in the market for something to carry your laptop in.
They have two more backpacks available but I am not even gonna link them cause they are ugly af. This (again somewhat overpriced) $44.99 sleeve is a cool accessory though and would go well with the Rogue backpack:
