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.

850 Down Fill

Certified 850+ 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.

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.

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.
