Adventuring in the mountains requires technical gear that we can trust. We Trust Mammut for their expertise in designing outdoor clothing and equipment for over 150 years. The Mammut Eigerjoch Light IN Hooded Jacket is one of our favorite jackets to wear in the high alpine due to its high warmth-to-weight ratio and its technical features. Filled with recycled PrimaLoft Gold synthetic fibers with Cross CoreTM technology, this jacket is warm, lightweight, and packable. The Cordura Ripstop exterior fabric is abrasion-proof and can withstand the abuse associated with climbing mountains. A PFC-free water-repellent treatment was added to the exterior to help shed any moisture, and the elastic cuffs and extended collar helps keep out the cold wind. Two zippered, harness-compatible pockets make stowing our essentials easy, and a helmet-compatible hood will fit over our climbing helmet for easy integration.
