The Mammut Men's Aconcagua Jacket is a stretch fleece jacket for warmth while tackling your favorite climbs. The Aconcagua is made with Polartec Power Stretch Pro, providing light insulation with a smooth outer face for abrasion resistance. Throw it on for a mild day on the local cliffs or wear it underneath your hardshell for mid-layer warmth. The single chest pocket keeps the overall weight of the jacket down and still provides a handy spot for your favorite granola bar. Slide your thumbs through the thumb loops for additional hand warmth as you finish out the day.
