In 1969, Seattle engineer and lifelong mountaineer Larry Penberthy formed Mountain Safety Research as a one-man crusade dedicated to improving the safety of climbing equipment. The fuel behind Larry's passionate fire was a simple belief that still drives our team today:
THE IDEA THAT BETTER, SAFER, MORE RELIABLE EQUIPMENT IS THE KEY TO UNLOCKING GREATER ADVENTURES.
From that notion evolved a pioneering outdoor company whose innovations have revolutionized the way people experience the outdoors worldwide. Today, we're a close-knit team still obsessed with designing the most reliable, high-performance gear possible, using our knowledge of engineering and science to find better solutions to the challenges of the mountains.
At MSR, we are engineers, tinkerers and passionate outdoor users–each with strong perspectives on how a product should work based on our own experiences in the wild places we love. But collectively, we believe that innovative solutions are bred by challenging convention, and that functionality, simplicity and reliability are the governing elements of enduring design.
Today, many MSR products are still hand-built on manufacturing lines just a floor below where we concept them.
And we're still driven to engineer gear for those who believe a trusted companion can be as simple as a 20-year-old stove that burns strong on family backpacking trips, to a water filter that provides the safe hydration needed to fuel the greatest expeditions into the farthest reaches of the globe.
