When that truly epic powder day finally hits, we keep the lodge dry-out sessions to a minimum and the face-shots to a maximum with the Burton GORE-TEX Ballast Pants. These two-layer shell pants feature a waterproof and breathable GORE-TEX membrane that not only shuts out moisture from snow, sleet, slush, and any other precipitation Mother Nature can dream up, but also allows internal moisture to escape to ensure that we don't overheat.
