Big-mountain heritage meets adaptability. We made the Men’s Mountain Light Triclimate® GORE-TEX® Jacket with best-in-class protection against a wide range of weather conditions. The two separate-but-integrated jackets can be worn three different ways depending on the weather and the mission. The GORE-TEX® shell jacket is snap-in compatible with a down-insulated liner jacket that’s also water repellent so you can get out there.
