Aenergy Air IN Hooded Jacket Men

A lightweight and breathable men's synthetic insulated jacket featuring Mammut LOOPINSULATION Active, designed for hiking, ski touring and high-output mountain activities.

The Aenergy Air IN Hooded Jacket Men is a lightweight synthetic insulated jacket designed for high-output mountain activities, from hiking and climbing to ski touring. Mammut LOOPINSULATION Active is engineered to remain breathable while moving and retain warmth when activity levels drop, helping maintain comfort through changing levels of exertion.

Mammut LOOPINSULATION Active uses 100% recycled polyester insulation made from 50% industrial rope production offcuts and 50% recycled PET. Zoned insulation places 60 g/m² through the body and 45 g/m² in the sleeves and hood, providing additional warmth around the core while reducing unnecessary bulk in areas that require greater mobility.

The stretch outer fabric and Athletic Fit support unrestricted movement. A close-fitting hood can be worn underneath a helmet, while the 2-way front zipper allows flexible ventilation and adjustment. Two backpack-compatible zippered side pockets and a chest pocket provide practical storage, while elasticated cuffs and hem maintain a clean fit. The jacket can also be packed into the supplied storage bag for easy carrying.
