When you’re cloud-high during shoulder season, the weather can be somewhat unpredictable. Make sure your sleep isn’t. This bag is stuffed with quality 600+ fill down for warmth down to 0° F, and protected with Marmot’s MemBrain® fabric for outstanding breathable comfort. We’ve updated the liner fabric, shape and baffle height for improved coziness and warmth.
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.
What is the EN 13537 test? EN, short for European Norm, is a government test for sleeping bags.
Has the feedback from the EN testing improved the designs of Marmot bags? Yes it has. The vast majority of our bags have tested to our current temp ratings. In some cases, the tests showed our bags were actually warmer than the rating we gave it. In another instance, there was a spot that showed room for improvement which led to more efficient baffle construction. With our baseline testing started in 2004, we can now measure improvement over time through new fabrics, insulation, and construction techniques.
Marmot rating vs. EN rating? Marmot's assigned temperatures are comparable to the EN lower limit rating. During Marmot's development process we send all samples to the Thelma Testing Center in Norway. Continually using the Thelma Center allows us to achieve continuity in our results.
