The Silence Proshell Trousers are waterproof shell trousers made from a three-layer fabric with four-way stretch. The trousers are fully seam-taped and the Hypershell® Pro membrane keeps the wearer dry in any weather. The ventilation zips on the thighs make the trousers versatile and the four-way stretch material makes them silent and comfortable. The ankle zips allow the trousers to fit over ski or hiking boots.
