Moving through the high alpine at a quick pace requires insulation that's breathable, mobile, and won't lose its insulating properties when confronted with the damp, snowy conditions that are intrinsic to the high mountains. Mammut's Eigerjoch IN Hybrid Men's Jacket can confidently check the box on all three of these requirements. Wind- and water-repellent Pertex Quantum Air fabric protects from spindrift, near-constant alpine winds, and light snowfall. Stretch panels--in the form of Ponterto Tecnostretch--along the underarms and sides allows your arms to move freely when you're booting up a steep couloir or working up a mixed route.
