The Access Hoody synthetic jacket by Black Diamond is ideal for keeping you warm on cold climbing days. Under the classification of a synthetic fibre jacket hides a complex and efficient material mix which guarantees maximum functionality. The lightweight upper material is made of wind and water proof Pertex Microlight 20D and is additionally treated with a DWR (Durable Water Repellent) treatment. Under the arms, Black Diamond used an elastic Schoeller nylon stretch, thereby increasing freedom of movement and breathability at the same time. The insulating layer of the synthetic fibre jacket is made of warming PrimaLoft Gold, which is protected in a migration-resistant structure against ""slipping"" of the insulating layer. The extremely light jacket can be stowed in its own breast pocket and comfortably secured on the integrated carabiner strap of the climbing harness or backpack. Even the insulated hood and two side hand pockets are designed in such a way that wearing a harness and climbing helmet is possible. The Access Hoody synthetic jacket by Black Diamond is the perfect outer layer for climbers. It provides warmth and allows for a full range of motion when climbing and also makes for a great insulating midlayer. "
