The Mountain Hardwear Warp Factor 3L Pant is built from a fully recycled nylon shell with a 3-layer DrySpell membrane, so it holds up on days when the weather refuses to cooperate. Inner thigh vents let heat escape on the climb, while an internal snow gaiter with a boot hook and an internal hem cinch keep the fit sealed over ski or snowboard boots. An adjustable waistband dials in the fit further, so these pants work as well on a summit lap as they do standing in a lift line. What Our Gearhead(R) Experts Are Saying:"I unzipped the thigh vents halfway up a skin track and felt the difference immediately, without ever second-guessing whether the shell would still keep me dry on the way down. That's the balance a real touring pant has to strike."
