ATV = All-Terrain Vehicle. The GORE-TEX 3L ATV Collection is for the skier or rider who doesn’t discriminate terrain or conditions. You can find flow, inspiration and creativity anywhere on the mountain, and your kit should embrace that. Featuring lightweight three-layer GORE-TEX fabric for durability and cross-venting for breathability, the ATV Jacket and Bib is designed to be a quiver-killer for backcountry and resort riders alike.
