Technology

EN Tested

Testing Center

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.



MemBrain®

What is it?

Marmot Membrain lamination utilizes advance technology that balances the best in performance of breathability, waterproofness, and water repellency with excellent durability. With a minimum of 10, 000mm / 10,000mm performance it's guaranteed to keep you dry and comfortable in the worst of weather.

How does it work?

Marmot Membrain technology offers excellent weather protection with interior comfort. The hydrophilic nature of the PU lamination reduces internal condensation and increases comfort range by reducing the chilling effect caused by converting condensation build up back into vapor.

What are the benefits of this technology?

This 2 Layer Lamination combined with superior face fabrics, create a soft, quiet waterproof and breathability fabric with superior performance. With excellent breathability, and long term durable waterproofness this advance fabric technology brings a new level of performance to value conscious consumers.
