I bought one of these with my 13. My old magentic Marsee starting to tear along the flaps (ya ya, I heard it when I said it).
Nice bag. Very roomy, but it does lack some interior pockets. Also they glue some vinyl and the underside over top of the mounts for the buckles to protect the paint. I guess they use some cheap glue that never really hardens as mine came off the first time I rinsed it off. I cut some cotten fabric from an old t-shirt and recovered them.
