One of outdoors’ most innovative brands, Klättermusen have created the Sigyn Crew a completely bio-degradable fleece mid-layer, therefore no microplastics into nature at end of life. Distinctive Klättermusen panelling, with their reflective triangles and embroidered branding to the chest. Shoulders, chest and top sleeves are one continuous piece; abrasion-free when wearing a pack. A soft micro fleece with some stretch, its low profile means it wears well under a shell. Completed with an extended back for increased coverage and an external locker loop for easy hang drying.
