Product Description

The Aenergy Air is intended for mountain days when you alternate between hard climbs and slower sections. Mammut LOOPINSULATION Active is designed to release excess heat and moisture during movement while retaining useful warmth when you ease off. A two-way zipper adds ventilation options, and the close-fitting hood works beneath a helmet. Its athletic cut layers neatly under a shell; it is an active insulation piece rather than a substitute for a protective outer layer in harsh weather.
