(Every month we offer one bag at a Really good price. This month it's the Trillium. Check it out it's a seriously nice and functional bag.) The clever modular design (3 cases in 1) computer bag system allows you to convert it in seconds from a comfortable backpack, to a vertical briefcase, to a lightweight, highly protective sleeve. The Trillium instantly unfolds to create a well-organized portable office for use on your lap or any desktop surface. Constructed of rugged expedition grade fabrics and the highest quality hardware, all stress points are reinforced, and like all of the finely crafted Higher Ground products, it comes with our lifetime warranty.

Check out this guy on Youtube. He posted some video on how the Trillium works http://www.youtube.com/watch?v=qYgCaAJDxS0
