I bought a set of Bohn Adventure Pants last week and tried them out today. They are an armor system that fits under your normal clothes. They have different materials that hold the armor depending if it is hot or cold out.  I have to say that they were comfortable under my jeans. I will be buying a pair of Kevlar jeans soon for abrasion protection.. I will be wearing them when I am doing errands or riding with a group that stops often. It is a pain to take my overpants gear off each time we stop.
