The Mountain Equipment W SIGMA JACKET has been setting standards for down clothing in the alpine sector for over 15 years. This high-end jacket combines low weight and compact pack size with high-quality 800 cuin goose down, which stays perfectly in place thanks to quilted chambers, thus preventing cold spots. The water-repellent, windproof, and breathable DRILITE® Loft outer fabric provides reliable protection from snow, ice, and wind—ideal for demanding multi-day expeditions and technical tours. The Active Alpine Fit, specially designed for alpine dynamics, guarantees full freedom of movement without bulky volume, while the insulated hood with patented Firestorm construction withstands even extreme conditions. Practical large storage pockets provide quick access to essential gear. The SIGMA JACKET keeps you safe, warm, and comfortable on every mountain tour.
