Mammut Aenergy IN

Designed for optimal temperature regulation, the lightweight and compressible Aenergy Hybrid insulation jacket is intended for mountain activities in cold conditions. You can wear it as a thermal layer under a hardshell or on its own as an outer layer. The unique Octa lining fabric, made from 100% recycled materials, provides the right balance between warmth and breathability at the front, shoulders, and sleeves. It insulates excellently even when wet and simultaneously regulates body climate by releasing excess heat. This allows for a wide temperature range to be covered without the need to add or remove layers. It is combined with a breathable, lightweight woven fabric that protects against wind, as well as windproof, lightweight inserts made of elastic storm fleece with a waffle structure for greater freedom of movement and breathability. The Aenergy Hybrid is the top choice for demanding activities in cold environments.
