Silver Winner In The Category Mountaineering
The Mammut Eiger Speed 18 combines two concepts that are rarely brought together in one product: the close-fitting stability of a running vest and the durability of a technical mountaineering pack. Developed for fast alpine movement, the focus is on efficient access, secure carry, and unrestricted mobility in technical terrain.
One of the defining features is its one-size construction. Using an intuitive side adjustment system, the pack adapts to a wide range of body types while maintaining a body-hugging fit designed to improve stability at speed. The vest-inspired harness keeps the load close to the body, while multiple quick-access pockets and a stowable bottom compartment support dynamic gear management on the move.
The Eiger Speed 18 received a European Outdoor Award 2026 for this combination of lightweight efficiency, running-vest-inspired comfort, and alpine functionality.
