It was first made for our Antarctic Expedition in 2011, and received its name as it protected us during the first ascent of Amundsen Peak. We can boldly state that this knickerbocker is the first truly technical knickerbocker ever made, and is the basis of our 3-PART concept. It is ideal for ski touring and expeditions small or big. The combination of 4-way stretch, waterproof and breathing capabilities ensures a combo of full protection and the comfort you need.
