Protective gear

Do any of you guys use protective gear other then helmets when you ski such as below?

By the way, for any of you who have consistent thumb or wrist injuries I thought of something. I'm an ex-boxer and I think boxing has something for you guys. As a boxer you hit solid surfaces with tremendous amounts of force (a heavyweight like me throws at about 1300 pounds of force per square inch). All that force impacts on the hands and neither the wrist or thumbs (when the thumb accidently gets caught) get injured even when you land at an off angle because your hands are very carefully wrapped by hand wraps. I know they have wrist guards out there and thumb stuff on gloves and poles as well but I can tell you from someone who has hit a heavy bag millions of times those things are jokes compared to the wrist and thumb protection you get from properly wrapped hands with boxing wraps (wraps not boxing wrist guards which are useless). So if any of you guys keep screwing up your thumbs or wrists you might want to get a pair of mexican style boxing hand wraps and learn how to wrap your hands. I gurantee they will protect you much much better.
