I got one of those ass savers, straight from
The Bike Snob himself at a book signing. It's got AYHSMB on it, and if you read his blog, you'll know what it stands for.
It's ok in a jiffy, but I think most people have a saddle bag under their seat to hold all the essentials so it may interfere. And in a shower, you're going to get wet either way. If you've got some heavy duty flexible plastic, you could probably make your own, feel free to trace mine.
