Marmot Plasma 30 Down Sleeping Bag - 30 Degree
This is it folks! Heaps of advancements in fabric, insulation, and design add up to the most evolved sleeping system on Earth. Incredibly lightweight Pertex© fabric forms a water-resistant, breathable barrier against the elements. 875+ fill-power goose down has been updated with our Down Defender treatment offering an extra level of moisture protection for sleeping bags exposed to wet environments. Flow Gate Construction allows warm air to circulate without allowing the down to shift.

What is it ?
Marmot Down Defender is an insurance policy for your down products. This specially treated highly water-resistant down offers an extra level of moisture protection for down exposed to wet environments. Down Defender helps prevent down from clumping and losing its loft when exposed to water, thereby greatly increasing its ability to keep you warm and comfortable.
- Stays drier 10 times longer than untreated down
- Maintains 150% more loft than untreated down in damp conditions
- Dries 30% faster than untreated down
- Treatment is PFOA and PFOS free
- Bluesign approved
How does it work ?
The treatment coats the individual plumes of the down cluster with a DWR (durable water repellent) at the molecular level. It puts a hydrophobic layer on each individual plume of the cluster. This treatment is done during the down cleaning process. The finish is extremely durable allowing the down to maintain its water repellency over 20 washes. The treatment also enhances the down's integrity and the durability of the cluster helping to increase its longevity.
What are the benefits of this technology?
Down Defender products stay drier longer, maintain their loft better and dry faster than conventional untreated down products.
Pertex Quantum® is the lightest down-proof by construction fabric available. It is a true featherweight at around 30g/m2 and uses the finest yarns available with the maximum thread count.
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.
How is the EN test conducted? First let's be clear that it is challenging to test temp ratings because there are so many variables. Every person will sleep differently in the same bag. Choices like clothing, sleeping pad, tent or no tent, eating and drinking before bed can all affect one's sleeping experience. For the EN test, a copper mannequin named Charlie is fitted with 20 sensors and a clothing layer (top, bottom, and socks) that provide a consistent thermal value. The mannequin is placed in the sleeping bag and put onto a wood platform roughly 12mm thick. The board is held above the floor with some support which allows air circulation under the board. The board is covered with a mattress that has a consistent thermal value then placed in a cold room. A mathematical formula is used to measure the data received from the sensors based on human modeling.
Why is there an EN Test hangtag on Marmot bags? Marmot sleeping bags sold in Europe require this testing and hangtag. We include this hangtag on all of our bags, as we believe it is the most reliable and accurate measure of the performance of a sleeping bag currently available.
How does EN testing differ from other methods and is it better? When Marmot first started testing bags, especially when we used Gore-Tex® fabric, our designers would go into meat lockers and sleep over night. Once they were able to sleep through the night they looked at the amount of fill to determine the temp range. Nowadays it is a bit more scientific. The testing method used in the US is very similar to the EN test. They use a copper mannequin, but the clothing, pad, and math formula are different. Again we feel the EN test is the most reliable and accurate measure of the performance of a sleeping bag currently available.
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.
Will the EN test become an industry wide standard? That is unknown. Currently our industry can't agree on how the testing should be done because of all the variables. The European government has stepped in and taken control of standardized testing. For the meantime, Marmot will continue to test with the EN standard.
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.
Wash & Care
Why do we encourage proper care of our clothing and gear?
Because you have invested in (or are thinking about investing in) one of the most technically advanced pieces of apparel or equipment you'll ever own and we want to make sure you have the information you need to protect and care for your purchase. Proper care assures you will optimize the performance of your Marmot product and maximize its service-life.
Sleeping Bag Care
- Hand wash warm, 105 degrees Fahrenheit or 40 degrees Celsius or machine wash Warm, Gentle cycle in a front load washer only.
- If you need to use a detergent, only use powdered form
- Rinse thoroughly
- Do not wring your sleeping bag
- Hang dry or tumble dry on low heat. If tumble drying a down bag, toss a couple of clean tennis balls in the dryer to help re-loft the bag
- After your bag is dry, store in a loose storage container. Cotton or mesh stuff sacks or extra-large pillow cases work well
- Do not store in a space where temperatures could exceed 125 degree Fahrenheit
- Do not bleach
- Do not iron
- Do not dry clean
