Move fast and light through the mountains in the Mammut Aenergy IN Hybrid Pant. Built with Pertex Quantum Air material, the pant stands up to the biting wind and snow when breaking trail up the skintrack. Polartec Alpha insulation provides warmth retention and breathability during active wear up and down hill. Side zippers on the pant provide temperature regulation to dump heat in the event of getting too warm. If approach crosses a crevasse field, or requires a rappel to the drop in point, the pant easily accommodates a climbing harness to safely reach a destination and complete the objective.
