Mammut Aenergy IN

Designed for optimal temperature regulation, the lightweight and compressible Aenergy Hybrid insulation jacket is intended for activities in the mountains under 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 entirely from 100% recycled materials, provides the right balance between warmth and breathability. It insulates exceptionally well even when wet, while also regulating body climate by releasing excess heat. This allows for a wide temperature range 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 increased freedom of movement and breathability. The Aenergy Hybrid is the top choice for demanding activities in cold environments.
