This purple Mammut Moench Advanced half-zip sweater is ideal as a baselayer for activities such as skiing, climbing and mountaineering. Made from Cordura yarn with waffle weave lining, it is abrasion-resistant and breathable with a high collar and long sleeves with thumbholes. As Marvin Gaye and Tammi Terrell would say, Ain't No Mountain High Enough for this Mammut top.
