Mountain Equipment Aerotherm Jacket - Men's
Mountain Equipment Aerotherm Jacket - Men's, Our go-to lightweight layer for active pursuits Mountain Equipment's Aerotherm Jacket helps our body maintain a comfortable microclimate when we're burning calories in chilly conditions. The softshell fabric provides windproof protection and breathability while being backed by a microfleece lining so we can stay warm without overheating as we're hiking running or climbing in the crisp mountain air. It also stashes away easily in our pack so we can wear it or shed it as needed as the weather changes or our activity level changes.
