Mammut Aenergy Insulated Hooded

The Mammut Aenergy Insulated Hooded Jacket is an exceptionally lightweight, packable insulation layer built for cold-weather mountain adventures. Responsibly sourced hydrophobic down with an impressive 851 fill power delivers outstanding warmth while remaining compact and low-profile.

Designed for female mountain athletes, it combines an ultralight recycled nylon outer fabric with small down chambers that help the insulation expand fully. An elasticated hood, pre-shaped sleeves, smooth YKK Vislon® front zipper and two harness-compatible zip pockets make it practical for demanding alpine movement, while the jacket can be stowed in its own side pocket for convenient backup warmth.
