Swedish outdoor brand Klättermusen has introduced its latest trail running capsule for Spring/Summer 2025, combining lightweight design, sustainability, and technical performance. Known for its mountaineering expertise and eco-conscious materials, the brand now brings the same rigour to gear designed for fast-paced movement on varied terrain.
The new pieces are intended for runners seeking freedom, flexibility, and protection, whether on short loops or long-distance trails.
“Your gear shouldn’t set the limits, it should expand them,” says Isabelle Liahaugen, Head of Design and Development at Klättermusen. “This collection is built to handle both quick miles and extended runs, with durability and detail at its core.”
