Jess, let me know what measurements you want and I'll make them for you.

I think they run larger for an x-small, since they still fit me (I'm not an x-small anymore!) and they're not stretchy. They don't have a huge amount of room to spare, but they're still comfortable. But yeah, I have 3 of them and I don't remember ever actually wearing them. But I'm keeping the red

It is the woman's model, it's just an old model since the switchbacks haven't been made for a few years.

I have heard that you definitely can't machine wash them.
