Thought I'd just jump in here and ask a question. I've seen people in the city wear backpacks that have this hard plastic shell in the back.
Looks sort of like a sled or something, regular sized backpack, but the back part is some cuvy shell. Looks cool as hell, anyone know the name of the company that produces it?
edit: uhm ok, the shell isn't the part that makes contact with your back... aside from that, I have a mental image, but hard to describe...
