Product information

The Eigerjoch IN Hybrid from the MAMMUT Eiger Extreme collection is a high-performance insulated jacket.

Stretchy fleece panels offer improved freedom of motion and breathability for backcountry ski touring and mountain climbing. The wool content has a naturally odor-inhibiting effect. The unlined Polartec Alpha Direct insulating material retains heat without excessive heat build-up, making it ideal for intense aerobic activities. The front pockets are easily accessible, even while wearing a climbing harness and backpack.
