I got them, and wore them on a ride for the first time yesterday. The medium is a tight fit but it feels like they will break in and get a hair looser. It was a sunny fall day, 12-16? and honestly they felt a little too warm for that weather. Which is fine! For the $23 I paid for them, I am pretty happy with them.
I don't think I would pay the $139 that F9 is now asking for them, though...
