Proven and tested in the field, it's a simple solution to the annoying brown stripe down the back of your pants.
The new and much improved ASO-3 is compatible with almost every standard rail saddle thanks to our new patent pending attachment system. The ASO-3 is a breeze to mount and once in place, it stays in place. When not in use, it can be folded up and stored underneath your seat, ready to be deployed the next time you are caught out in a shower. The new design have also resulted in a more durable product that is less sensitive to wear and tear. So whether you're urban shredding, winter training or just prefer to keep your behind unsoiled, the ASO-3 is your new best friend!
