I have a set of ProStock inflatable fenders 16"Ø X 42" long. They deflate quite flat/small for storage in their own bag. Very 'robust' even that they're made of a nylon (?) coated fabric duck material. They are supplied with their own pump for inflation/deflation. Expensive, but all large fenders are expensive.

They saved my butt a few times when docked during storms, including H. Irene.
