I actually really like the Bohn armor, it is more comfortable that I had expected it to be. I have found that it works best under pants that do not already have armor in them (like most leather riding pants). Once you have it on, the armor doesn't move around and I find it comfortable for all day rides. I did 300 miles last Sunday to the mountains and back and had no issues. Prior to the Bohn armor I was wearing motocross knee/shin guards. I like the Bohn much better.
I got the Bohn armor last fall, so I haven't really tried it out in the dead heat of the summer. I am thinking it might be a bit much for the 90+ temps and high humidity of an NC summer. Bohn does make a version that is mesh that looks like it might be better for summer, but I am hesitant to purchase that without seeing it first.
