From an easy hike to a long day of ski touring, the Mammut Aconcagua ML Hooded Jacket is ready to take us on any adventure. It features the breathable, moisture-wicking Polartec Power Stretch Pro fabric to keep us comfortable while also offering superior freedom of movement and abrasion resistance. Ideally used as a midlayer, this cozy fleece jacket features thumb loops to keep our sleeves in place as we slip extra layers on top.
