The Cold Forge Hoody down jacket by Black Diamond quickly turns an icy belay station into a nice, warm comfort zone. On alpine activities, it can be used either as an outer layer or as a warm midlayer under a shell jacket. The outer material made of strong, lightweight Pertex Microlight 20D not only protects against wind, but is also highly water-resistant with its DWR (Durable Water Repellent) treatment. A pleasant warm feeling and high insulation performance is provided by the PrimaLoft Gold Insulation Down Blend filling. This high-quality insulation material combines in a highly efficient material mix the warm and water-repellent properties of both materials. Of course, Black Diamond uses downs that are VDS certified and therefore it can be checked exactly where the downs come from. The additional inserts under the arms and the helmet compatible hood, which ensure that the climbers and Alpinists do not freeze in ice and snow, make the Cold Forge Hoody Down Jacket climbing compatible.
