The Mammut Aenergy Light ML Half Zip is a lightweight long-sleeve top for ski touring, mountaineering, hiking, and trail running. It is designed to be worn either as a functional baselayer or as a lightweight midlayer during high-output mountain activities.

Polartec® Power Grid™ combines excellent breathability with efficient moisture management to help maintain a comfortable body climate during intense activity. Its distinctive grid construction retains warmth without adding unnecessary bulk while keeping weight to a minimum. The long half zip allows for rapid ventilation on demanding ascents, and flatlock seams enhance comfort by reducing chafing beneath additional layers.
