My under the seat bag will just look like a leather bag with a clip strap at the top. It sits in a bag holder.....it must have fallen out. It has a San's emergency bottle, a quick link and a Specialized EMT tool. There was a red blinker light attached to the portion of the bag that is still connected to my bike. It is gone also. They may be in the same area...
Let me know if you find it.
