You do the same thing I do when I poop, pull em down.
I've tried wrist guards, Level gloves (ech), full face helmets, padded shorts, kneww pads and various assorted race (ski and board, not MX) armor.
After limited success, changes to my mobility and the hasal factor, I'm down to a good, non full faced helmet. My wrists and arms get ust as banged up with guards as not, kneww pads slip and rotate during falls, and padded shorts never seemed to help with normal carving/freeriding. I've considered a turtle shell, but wonder if it will be another piece of gear I just don't wear.
