Mammut Aenergy Light SO Pants softshell trousers - black size: xl

Typical softshell trousers force a choice: accept extra weight and bulk for protection, or sacrifice weather resistance to move fast. The Mammut Aenergy Light SO Pants eliminate that compromise. Built with an ultra-light Mammut SOFtech™ fabric, these pants deliver wind resistance and durable water repellency in a package that weighs next to nothing. The athletic fit and 4-way stretch allow unrestricted movement on technical terrain, while the PFC-free DWR finish sheds light precipitation without harming the environment. From high-alpine traverses to long rock routes, these pants keep you protected, dry, and moving at full speed.

In daily use

On the trail or the wall, the Aenergy Light SO Pants move with you. The high elastane content and gusseted crotch eliminate binding, so high steps and stemming feel effortless.

The PFC-free DWR means you can push through damp brush or light showers without worry, and the UPF 50+ rating protects your skin on exposed ridgelines. When the day is done, these pants pack down small enough to stash in a summit pack—ready for the next objective.
