I just bought the "Spring 2010" model on sale at REI. I could only find Small but they seem to fit OK (generally wear a M). I have NO idea how you're supposed to drop the tail enough to pee...seems impossible. I have not worn them on a ride yet bc it's been hot/raining every afternoon and then I injured my groin/quad at Zumba. Maybe I'll give them a whirl this weekend. I don't know that I'll be able to drop them though.
