Athletic fleece jacket made from Polartec Power Stretch Pro fabric
The Aconcagua Midlayer Jacket from Mammut is the perfect fleece jacket for every athletic situation. Already in its third generation, this jacket has proved itself on small and large outdoor adventures alike and can even join you on expeditions. With its Polartec Power Stretch Pro fabric, it is extremely stretchy and very movement-friendly.
Stretchy fleece jacket with excellent freedom of movement
This Mammut fleece jacket is particularly breathable and quick-drying, allowing it to efficiently wick away moisture from your body to the outside. This makes it perfect as an insulating mid-layer and a reliable all-rounder for a wide range of outdoor activities.
Some other great features are its raglan sleeves, zipped side pockets and a high collar that completes the athletic cut of the Aconcagua Midlayer Jacket. Last but not least, the Mammut fleece jacket is bluesign certified and made in Europe.
