Perfect for cold, active days when you need a bit more warmth than a shell jacket can provide. The Expedition X-Lätt Jacket has just the right amount of ultra-light insulation you need to stay warm when your body heat isn't enough. Made from soft material made of recycled polyamide, it is perfect as a mid-layer for cold winter adventures or on its own during warmer days. The lightest member of Fjällräven's Expedition Series.
