GORE-TEX snow pants made from recycled polyester. The Quiksilver Altostratus Stretch GORE-TEX Bib Pants feature a breathable and waterproof shell design. They provide incredible freedom of movement and stay soft and supple thanks to strategically placed brushed tricot zones. Their zips are waterproof and your avalanche transceiver can be stored in its own chest pocket. Made from recycled polyester, these snow pants have a high stretch content and should be worn with an extra layer underneath on very cold days.
