I always wear a armored shirt, kidney belt and knee/shin protector if we go dualsporting.
The knee protectors did an excellent job yesterday when I tried to cross two trees at once (I should have known better). Long story short, I took a good spill and dented my knee protector permanently.... I didn't even feel it. The only "injury" I have is a hurting right boob

(my chest plate is cut for men).
