"Ski poles, also referred to as poles (in North America) or sticks (UK), are used by skiers for balance and propulsion. Modern ski poles are most commonly made from aluminum and carbon fiber, though materials such as bamboo are still used. Poles are used in alpine skiing, freestyle skiing (with the exception of aerials), and cross-country skiing. Ski jumpers do not use poles." - (en.wikipedia.org 28.09.2019)
