This heritage jacket was created in collaboration with the British cult designer Nigel Cabourn. Inspired by the 1969 first ascent of the Japanese Direttissima route on the Eiger, the design is based on an original puffer from the period. The outer shell is crafted from durable Pertex® Quantum fabric – a lighter, modern version of the original downproof fabric used for expedition clothing. The vintage look is complemented by an embroidered Mammut Garantie logo, two patch flap pockets and a fleece-lined side entry pocket. The Mammut x Cabourn Direttissima IN Hooded Jacket embodies the spirit of a pioneering era in mountaineering.
