I'm on my 2nd HD set, 1st set I sold after I traded my RKC for the Ultra, Than we bought a 09 RKC and had to have them again, both are the quick disconnect type, I would stay away from the snap button type, they take longer to put on and seem to shrink, also making them harder to reinstall. They help keep you warmer and drier, I have ran with them on the hiway for short distances, engine didn't seem any warmer when getting back off hiway at the first stop. When removed you just roll them up and store them in the saddle bag, I use rubber bands to keep them roled up.
