When I worked for the ski school in Niederau, there were no mountain first aid men, it was left to the instructors to deal with accidents and injuries. We were trained to set broken legs, ankles, wrists, etc, and then transport the unfortunate person down the mountain.
So that stripe down the leg of the ski pants was quite a thoughtful piece of design.
It lets you understand, when straightening the leg, if you should twist the foot to the left or to the right....
