Obermeyer reaches out to the discerning, dedicated skier with the Trilogy 3 In 1 Jacket. Designed for skiers that ski through it all, the Trilogy has both a 15K waterproof-breathable stretch shell and a zip-in insulated stretch fleece jacket. This gives you the option of wearing them together or separately, depending upon what the weather is doing. The outer jacket includes a built-in ventilation system, Snap-Away powder skirt, built-in neck gaiter, and removable hood. The insulator easily doubles as a light jacket and includes zippered hand pockets, stretch fleece panels and articulated sleeves.
