my knee armor keeps breaking on the sides, b/w the main front part that covers my knee and the sides, when I bend my knees... "so don't bend your knees!" yeah, well, that doesn't work. I want to use some kind of rubber and place it b/w the 2 pieces so that when I do bend at the knees, the side piece can bend outwards...
but what material should I use? has anyone done this?
edit: my spelling sux
