Klättermusen's Mysse is a functional and durable hat that's ideal for Scandinavian winter. Fully waterproof and windproof thanks to it's 3-Layer construction, it protects your head and ears from the wet and cold, and your eyes from rain and sun. Crafted from bluesign® approved bio-based nylon that is highly breathable, it features a wool/polyester lining inside that helps to retain heat while also making it quick-drying when wet. The adjustable chin strap keeps the hat in place in windy weather, and reflective details on the front guarantee visibility in low-light conditions.
