800 Down Fill

Certified 800+ Fill Goose Down bags are constructed with the following features:

• Nautilus Hood: the same construction as our 8000m jacket hood, a 3D hood that
  wraps around your head and reduces heat loss.
• Hood Muff: creates a warm down gasket around your face, keeping the drawcord
  away from the face.
• Stretch Tricot Baffles: allow the bag to be stuffed and unstuffed without tearing the baffle material.
• Trapezoid Foot box: matches the shape of your feet, wider in the toe area and narrower in the heels.
• Down Fill Oversized Draft Tube: eliminates cold spots
• Zipper guard: keeps the draft tube fabric from getting caught in the zipper
• Ground Level Seams: top layer wraps fully around the body creating a warm layer of down.

Down

From the beginning, down has been Marmot’s foremost insulator. No synthetic surpasses the lightweight, compactability and longevity of down.

Our down is independently certified to ensure the quality and fill power. Due to our rigorous testing, we are confident that we are supplying the finest quality down available from anyone, anywhere.

EN Tested

Facts don't lie!
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.

How do I read the EN hangtag?

Basically the EN hangtag shows a temperature range:

Comfort Limit – Based on a standard woman having a comfortable nights sleep
Lower Limit - Based on a standard man at the lowest temp to have a comfortable nights sleep
Extreme Rating – A survival rating for a standard woman

For example, the rating on our Pinnacle 15º Sleeping Bag shows:

Comfort Limit – 22.2 degrees
Lower Limit – 10 degrees
Extreme Rating – Minus 24.7 degrees

This can be helpful in selling on the floor. Below is an example dialogue between a female customer and a store employee.

Female Buyer - “I think I need a 15 degree bag.”
Store Employee – “What temperatures are you expecting on your trip?”
FB – “Between 15 and 25 degrees. I tend to sleep cold however.”
SE – “You can definitely use this Pinnacle 15 bag, but you may consider buying a Zero degree bag to sleep more comfortably at the lower temperatures.”

Marmot rating vs. EN rating?

Marmot’s assigned temperatures are comparable
to the EN t-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.
