I'm looking for a bag that I can take my books in (usual one or two CS textbooks) and my laptop. I'm partial to courier style. Problem is i don't want to spend a lot. Someone was telling me about sleeves you can buy that are made out of neoprene, would that work in any bag, like my current courier bag?

Something like those?

yeah something like that, but will it protect my laptop in my regular couriers bag?
