    Mammut strives to ensure fair and safe working conditions in all factories making its products. To systematically improve working conditions throughout its supply chain, Mammut was the first outdoor brand to join the Fair Wear Foundation.


The Aenergy IN Shorts Men are insulating shorts for an extra layer on cold ski touring days and/or for downhill skiing. Thanks to the zippers on the sides, which are continuous from top to bottom, it is easy to quickly pull on the shorts over ski tour pants at the summit. So the pants provide protection against wind and cold conditions that extends to over the knee. Stretch inserts provide more freedom of movement. The Aenergy IN Shorts Men impress with their lightness and high-quality materials, which include Pertex Quantum and Primaloft. Practical: If needed, the pants can be packed away in the integrated pocket.
