We love an Indian summer as much as you do, but sometimes the fringe seasons aren't as ideal as you want. That's why the Never Summer's water-resistant down, rated for temperatures as low as 0° F, ensures warmth amidst the vagaries of shoulder-season weather.
The Never Summer an ideal choice for trips, climbs and treks when sub-freezing weather is imminent. Certified 650 Fill Power Down with Down Defender to Improve Water-Resistance in Wet Conditions. Anatomical Wrap-Around Footbox Increases Insulation and Room for Your Feet, More Warmth and Comfort. Full Length Locking YKK Two Way Zipper with Anti-Snag Slider reduces fabric snagging. Down-filled Collar with Easy Access Draw Cord.
Internal Stash Pocket and Heater Pocket in Footbox. 30d 100% Nylon DWR 1.18 oz/yd, 30d 100% Nylon Ripstop DWR 1.5 oz/yd. 650+ Fill Power Duck Down. 30d 100% Nylon DWR 1.27 oz/yd. Comfort: 13.6°F / -10.2°C.Lower Limit: 0°F / -17.8°C. Extreme: -39.8°F / -39.9°C. Bag Dimensions (Shoulder x Hip x Foot). 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. 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. How do I read the EN information? In this example, if a woman who sleeps cold is planning a trip with expected lows between 15 and 25 degrees, she could definitely use the Pinnacle 15 bag.
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? 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? The vast majority of our bags have tested to our current temp ratings. 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? 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.
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.
Why do we encourage proper care of our clothing and gear? Proper care assures you will optimize the performance of your Marmot product and maximize its service-life. 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. 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.
