Oxford brand Tank bag. Mid-sized bag with good strong magnets, works on both C10 and C14. Ample main compartment, zippered top with map pocket, side pockets too. All zippers in good shape. Black with blue and reflective silver accents. Black is a little faded, but still serviceable. Has a strap that can go around triple tree if desired. I won't claim water "proof" but after lots of riding in the rain stuff inside has always been fine. Never left on bike out in the rain though.
