This updated version of the popular Aconcagua sees a change of fabrics resulting in a lower weight without a lose of quality or performance. It is still a comfortable and technical mid layer you'll be happy to wear all day on and off a mountain.

Mammut says:

The Aconcagua Light hooded jacket can be worn as a mid-layer for mountaineering, climbing, ski touring or hiking. The high-quality material is lightweight, stretchable and pleasant to wear. The design of the pockets is tailored to the needs of mountain sports enthusiasts: allowing easy access at all times, even when wearing a backpack or climbing harness. A versatile and comfortable mid-layer hooded jacket.

Mammut's 2021 Aconcagua Light ML Hooded 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, waist or hood. 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 a new fabric and with a ribbed design to allow more effective temperature regulation when hot or cold. It is comfortable, looks great and actively wicks moisture away when you start to heat up. This is a Bluesign certified product meaning it has been manufactured in a sustainable way limiting the impact on the environment where possible.
