EN Tested

Marmot began as a sleeping bag company and we continue to pioneer performance, value and insulation standards in the outdoor industry. All Marmot sleeping bags are EN tested to ensure quality and performance. During the development process, we send all samples to the Thelma Testing Center in Norway. We continually use the Thelma Center to achieve continuity in our results. EN 13537 is a European standard designed to standardize the temperature ratings on sleeping bags manufactured and/or sold in Europe. It went into effect on January 1, 2005. There are three main temperatures that are measured, Comfort, Lower Limit or Transition, and the Extreme/Risk range. Comfort Range indicates the average person will feel comfortable at all times. Transition Range indicates an experienced person can adapt to the cold conditions by wearing more appropriate clothing. Different values for men and women are the norm. Extreme/Risk Range indicates a strong sensation of cold has to be expected, there is a risk of health damage by hypothermia. An experienced person can adapt to the cold conditions by wearing more appropriate clothing.
