Cyclists: Topeak AirFender Keeps Water and Mud Off Your Back

Topeak, further bringing the comforts of home to cyclists everywhere, now whips out AirFender, an inflatable rear fender that slides onto your bike's seat post.

When rain hits, a few strokes of a pump inflates it, and it sticks up like a turgid schlong, keeping that telltale skidmark of water and mud off your back for the duration of the storm. Neat trick.
