The Vario Rain Cover ($95) from Wunderlich is expandable and fits nearly all tankbags. Instead of elastic sewn into the base, the Vario cover uses an adjustable elastic drawstring to keep it in place and a hook-and-loop strap to keep the cover tightly fitted around the tankbag. The see-through top shows your map pouch and the cover can also be opened via a waterproof zipper, allowing riders to access the contents of the tankbag without removing the rain cover. Wunderlich also offers a rotatable and removable Map Pouch for Elephant Tank Bags ($45) that can be attached outside the rain cover.
