Fully featured and rearing to go, Mammut"s Lanin Jacket is a bomber piece of alpine gear that you will take with you everywhere. Extremely light, this 3 layer GORE-TEX Active Shell jacket lacks nothing in protection and performance. Pit zips allow you to dump excess heat on tough climbs while pre-shaped arms and an adjustable hood, hem, and cuffs dial in you fit to match your layers and activities perfectly.
