What a nice, smaller tank bag. Just right for some gloves, pair of sunglasses, microfiber cloth, owners manual, flashlight, Leatherman, neck gaiter, and a few other smaller items. The zippered exterior compartments are very handy for glass cleaning cloths that I use to clean my TFT display. The bright yellow interior makes it hard for things to get lost.The expandability is handy, just in case you need a bit more room. It does offer a port for running a power cord in, handy if you need it.The tank ring mounting keeps it up off the surface of the tank, making it impossible to scuff the paint. Same ring is very easy to install and easy to remove bag for refueling.Overall, excellent quality, stitching, zippers and other materials are first class. If needed, I'd buy again.
