The Aconagua Light is a comfortable mid layer you'll be happy to wear all day on and off a mountain. This is a lightweight, technical mid-layer that excels in the hills.

Mammut says:

The mid-layer you can rely on in the mountains: The Aconcagua Light ML Jacket Men is a functional jacket tailored to mountain conditions. The lightweight, comfortable and stretchable material with high breathability will help you conquer ascents and descents. The flat design of the seams makes it feel very comfortable to wear and avoids chafing under a backpack. A technical mid-layer placing top priority on good performance.

Mammut's 2020 Aconcagua Light ML Jacket is a streamlined mid layer designed to keep you comfortable when on the move. The jacket is quite a slim fit but stretchy and very soft on the skin. This jacket is light on features to keep the weight down. There is a single small chest pocket. There is no adjustment on the cuffs or waist. This stripped back design is ideal for layering and keeping the weight and packsize to a minimum.

The most recent update has seen a switch to Pontetorto Technostrech fleece which is a fantastic fabric. It is comfortable, looks great and actively wicks moisture away when you start to heat up. This is a Blue sign product meaning it has been manufactured in a sustainable way limiting the impact on the environment where possible.
