I'm looking for seat covers for the sports seats on my TT. I'm wanting them first and foremost to protect the seats from both wear and sweat. I am a cyclist and after a ride I am not able to shower before driving home. I've looked online but everything I am finding looks like an empty sac of potatoes thrown over the seat.

 

You are going to have to find an automotive upholstery store to make a set of seat covers.
