Mammut is a long-established outdoor brand founded in Switzerland in 1862 as a rope manufacturer. Starting out by manufacturing agricultural ropes, the company expanded into the field of climbing ropes and mountaineering equipment after its strength and reliability gained recognition among mountaineers. The high level of safety cultivated through climbing ropes continues in today's apparel, harnesses, helmets, and backpacks. Mammut's distinctive offerings include shell jackets that were among the first to incorporate waterproof, breathable, and softshell materials, as well as the "Eiger Extreme" series designed for snowy mountain climbing. Signature items include alpine hardshell jackets, durable mountain boots, climbing ropes, and harnesses, and are popular with both professional alpinists and casual climbers.
