Ok, I have a friend who is a tennis official. It's often cool in the
morning and then gets hot during the day. What do you call those pants
that have a zipper or something and convert from long pants to shorts?
I was trying to explain there to her, but I couldn't remember what they
were called. So if anyone can help me out of this senior moment, I'd
appreciate it, and so would she :)

Thanks!
Carole
