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. MSR has strong perspectives on how a product should work based on their own experiences in the wild places they love. They believe that innovative solutions are bred by challenging convention, and that functionality, simplicity and reliability are the governing elements of enduring design.
