I have to say that I was not very impressed, in fact I was pretty mad, with the protection that my Fox brand knee/shin guards gave me. I was riding trails and came across a nice area to jump. Someone took our their camera to get some shots (you all know what happened next). Long story short....I land and go over the handlebars. Luckily nothing was broken I had all my gear on and did manage to scratch up pretty much everything. But I was wearing my knee guards and still managed to get a rock directly on my kneecap which is now bruised pretty badly. That could have been bad news. I have those knee/shin guards that strap around your calf, and sort of hang/flap over your kneecap. I think I'm switching to some rollerhockey or skateboard knee protectors that have staps on both sides of your kneecap. Who knows, maybe it would have been worse had I not been wearing them, but I'm not sure they did any good, anyone else?!?
