NEXTIn 1973, when dehydration was identified as the main cause of Acute Mountain Sickness, MSR developed the world’s first remote-burner stove to help mountaineers combat high-altitude malaise. The Model 9, designed to efficiently melt snow for drinking water at high altitude, became, almost immediately after its release, essential equipment for mountaineers around the world. But it was loud. To maintain the solitude of the outdoor experience, MSR developed the Whisperlite backpacking stove in 1984 to operate without the roaring hiss of the Model 9.
