The Aconcagua Light Midlayer Jacket Women's by Mammut is a stretch fleece designed as a versatile midlayer for outdoor pursuits. It sits comfortably under a shell or can be worn on its own when temperatures dip, providing core warmth without adding bulk.

Constructed from lightweight, elastic fleece, this vest moves with you whether you’re hiking, climbing, or simply exploring the outdoors. The full-length front zipper allows for quick temperature regulation, while the streamlined, hoodless design ensures smooth layering beneath a backpack harness or jacket collar.
