Wave Construction™
From a side cutaway view of the sleeping bag, looks much like a suspended ocean wave of insulation or an “S” from the bottom quilt line to the top quilt line. Wave construction offers the advantages of both traditional blanket and shingle construction, but produces more stable and higher loft than either with no significant increase in bag weight.

A-Flex™ Lite Construction
Advanced shingle construction utilizing the Anchored Shingle System™ optimizes loft and heat retention while minimizing excess weight.



DOWN BAGS

Down
From the beginning, down has been Marmot’s foremost insulator. No synthetic surpasses the lightweight, compactability and longevity of down.
We are proud to use the best down available in our sleeping bags: 850 fill power, 800 fill power and 600 fill power.
850 / 800 Fill Power Goose Down - from the best sources in Eastern Europe we have cornered the market on some really old birds, the Mother Goose. These geese are used for the farmers’ personal food supply and are much older than the geese normally raised for market. Avg. age is 1-3 yrs. And these big honkers make mean old’ watch geese too.
Older geese produce mature down with larger, stronger and longer lasting down clusters. Many high fill power downs are mostly highly processed Chinese down with high cluster % but from younger Chinese birds that will not maintain loft over time.
The difference in 850 fill is the selection of only the best of the best and the careful processing to assure the finest down available.

General down guidelines:
550 to 600 fill power - Mostly Chinese birds processed at 12 weeks, blended with European
625 to 650 fill power - Mostly European birds processed at 12-16 weeks
700 to 750 fill power - Mostly European birds processed at 16-20 weeks
800 fill power - All European with the addition of mature down from the Mother Goose
processed at 24-48 months
850 fill power - Carefully selected, blended and processed from each lot of Mother Goose

Hypoallergenic - some people think they are allergic to down. In fact, they are allergic to the dust and other foreign material in down and feather products that are not cleaned thoroughly. Our 800 and 850 fill down is so meticulously cleaned and processed that it is hypoallergenic. Significantly reducing the chance of allergic reaction.

TESTING - As always this down will be independently certified and undergo a second test when it arrives at our door to assure the quality and fill power of each and every 800 and 850 fill power down bag we make.

Our minimum spec 850 / 800 cu in/oz, as tested independently and re-tested by us.
Due to our rigorous testing we are confident that we are supplying the finest quality down available from anyone, anywhere.
