SmartWool undoubtedly named the Corbet 120 Jacket after the Corbet's Couloir that brave skiers point their planks down. If you don't know about the couloir, it starts off steep, then turns into a full-on cliff, with a nice landing that shoots you through the actual couloir. There are hours of entertaining footage showing skiers tomahawking out of the couloir. Enjoy these videos all year round, and when it comes time for you to hit the couloir, zip into this warm midlayer before you even get in line. If you blow the landing, at least you can take comfort in knowing that you'll stay warm while you somersault down the mountain.
