Eclipse sportpack tankbag 200 series installed on Gypsy. I highly recommend this tankbag because it is expandable, stable, durable, comes with a rain cover and a map case that snaps to the top. This is the third one I've owned in 23 years. I've owned this particular tankbag for 6 years and I use it every single day. This view shows the straps attached to the back. I feed the strap below the gas tank where the tank is bolted down and it adjusts at the top. When this strap is tight the tankbag is very secure and does not slide around at all.
