Mountain Safety Research, MSR, is a manufacturer of camping, hiking and mountaineering equipment such as portable stoves, water filters, snowshoes and tents. Although MSR’s gear specializes in lightweight and technical gear, it’s designed for a wide range of outdoor enthusiasts, from beginners to experienced mountaineers. MSR was founded in 1969 and is headquartered in Seattle, USA.


MSR originally started as a newsletter in 1969. It covered topics related to mountain climbing safety. Later, in 1973, Larry Penberthy developed the MSR Model 9 camp stove, which was relatively efficient in cold weather. He separated the stove’s burner from the then small fuel tanks and then pressurized auxiliary fuel bottles into the tank and used a better windshield. This evolved into the Whisperlite stove, a multi-fuel stove that can run on a variety of liquid fuels.


Penberthy also designed an ice ax that was supposed to dig ice better and stop the slide. Penberthy also introduced ice letters with metal stems; metal axes have replaced the earlier wooden handles. This is where the story of MSR products began.
