Norrona Falketind Octa lightweight breathable insulation jacket is made for all-year mountaineering but works great for general outdoor activities all year, from trekking to ski touring. To provide optimal protection, insulation, and breathability, Norrona uses a special Octa lining and a premium lightweight aero60, recycled nylon Pertex face fabric (45g/m2) that offers comfortable stretch, wind resistance and breathability. Side panels and cuffs made in flexible warm1 material ensure a good and athletic fit, breathability and prevent bulkiness. The Octa lining (80g/m2) construction and multichannel fibers are very open, allowing a continuous release of body heat to keep you comfortable during your activities. This provides great insulation, excellent breathability, and quick-drying even when wet. Key features include a warm and weather protective collar, two spacious mid-mounted pockets, and one-handed elastic adjustment in the hem. The jacket has a technical fit with a Y-cut and articulated arms for good movement while climbing. A longer cut in the back ensures extra protection.
