First established in the 19th century the very beginning of the classic alpine climbing era, a small Swiss company grew over the next 150 years to become one of the sport's household names: Mammut. If you are a climber, then chances are you have relied on the products of Mammut. Now to celebrate the 150th anniversary the company has instigated a massive global project involving climbers all over the world, from beginners to professionals in a series of expeditions.
