I've had the Kevlar jeans for about a year and a half. The top part is a little tall so I have to pull them way up and use a belt to keep them in place above my hips. I don't really mind this though because I figure I'll be a little better protected in a get-off.
My knee armor rides low and that's always bothered me a bit since I'd kind of like it in the right place in the event that I need it. I'm in CA with a bike for the holidays so plan to ride down there next week and have Wayne move the knee armor up a bit.
