Being a part of Mammut’s Eiger Extreme line, the Eigerjoch IN Hybrid Vest is a high-performance midlayer ready for high alpine objectives. The air-permeable Pertex Quantum provides a high level of breathability while effectively sealing out wind and providing a level of water-resistance. Inside the vest, Polartec Alpha helps enhance breathability while also adding critical core warmth when you’re at rest. Putting the proverbial cherry on top, Mammut finished this well-designed layer with merino Tecnowool panels along the sides and back.
