Skiing is inherently dangerous and though I do not ski nor have I ever skied I assume that injuries such as broken collar bones and dislocated shoulders could be a problem. In the sport of Rugby we do not wear heavy pads like they do in American football but many Ruggers wear light weight chest and should protection pads that are designed to wear as a shirt. Perhaps this could be implemented as a precautionary measure for skiers and perhaps it could be augmented to provide a bit of extra warmth for those frigid days on the slopes.
