WHY USE MOUNTAIN SAFETY RESEARCH?
MSR has always been a company of engineers, inventors and unruly dreamers. Larry Penberthy started the company in 1969 on a personal crusade against unsafe equipment. Today, we’re still an intrepid team obsessed with creating the most reliable, high-performance gear possible.

Whether it’s defying the status quo in equipment design or radically shifting the social mindset, we believe the greatest innovations—and explorations—are inspired by the world’s unruly dreamers.
