Mammut Aenergy IN

Designed for optimal temperature regulation, the lightweight and compressible Aenergy Hybrid insulation jacket is designed 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 100% recycled Octa lining on the front, shoulders and sleeves provides the right balance of warmth and breathability. This insulates superbly even when wet and at the same time regulates the body climate by releasing excess heat. This allows you to cover a wide temperature range without having to take off or put on layers. It is combined with a breathable, lightweight woven fabric that protects against wind and also windproof, lightweight inserts made of elastic storm fleece with a waffle structure for more freedom of movement and breathability. The Aenergy Hybrid is the first choice for demanding activities in cold environments.
