These are a bit tighter than expected, but comfortable and flexible. They feel a bit like a wetsuit, and don't breathe very well. I tend to carry these on climbs and put them on for technical descents.
I am that crazy 44 year old women who has been addicted to bikes since my first bike. I have actually gotten better (riding) the older I get (crazy). Anyways, I tend to attempt things that only expert crazy mtn bike riders should be doing. I whined up hiking-a-bike. But, I do crash (more like fall over) a good bit. So I felt I needed some protection. These did the trick.
