Mammut Aenergy Insulated Hybrid

The Mammut Aenergy Insulated Hybrid Jacket is a lightweight, compressible insulation layer built for cold mountain activities. Its hybrid construction combines wind-resistant fabric with stretchy storm fleece, delivering warmth, breathability and unrestricted movement.

Octa insulation helps regulate temperature and retains warmth even when wet, while practical details such as a two-way YKK Vislon® zipper, climbing-harness-compatible pockets and thumbholes support demanding outdoor use. It suits mountain users who want a versatile layer beneath a hardshell or as a standalone outer layer.
