Marmot Plasma 30 Degree (2013) Sleeping Bag

Weighing less than a pound and a half, the high performance Marmot Plasma 30 Degree down sleeping bag offers mild weather backpacking versatility! Premium 900 fill power goose down insulation and Flow Gate technology baffling create an extremely lightweight, compressible package for backcountry adventure. The Plasma 30 Degree is insulated with certified 900 fill power, European goose down. Fill power measures the loft or fluffiness of down insulation and Marmot goes to great lengths to guarantee the 900 certification with a battery of in house and external verifications. Renowned for their efficiency in retaining heat and compressible properties, down fibers have an incredibly soft, comfortable feel and, despite advances in synthetic materials, continue to provide the best warmth to weight ratio of any insulation available. The one weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet. Flow Gate construction is used in the Plasma 30 Degree sleeping bag to provide better thermal value and increased weight reduction. Strategically placed Flow Gate baffles eliminate lateral and vertical down shifting by using vertical chambers with Flow Gates to control the position and density of the down insulation. This technology also enables the user to manually shift the down to preferred locations, customizing the sleeping system to each individual. Wrap around foot box construction incorporates the Flow Gate design with Marmot's classic, trapezoidal shape for increased warmth and a comfortable fit.Despite its lightweight construction, the Plasma 30 Degree makes no sacrifice with regards to performance and features. A contoured, ergonomic hood, insulated draft tube and insulated collar around the neck area seal out cold air and feel soft and comfortable against your skin. Two way zippers sliders offer venting options and zipper guards help to avoid irritating and damaging snags.The Marmot Plasma 30 Degree sleeping bag is available in Regular fits up to 6'0 and Long fits up to 6' 6 lengths. A stuff sack and storage sack are included. Long Left Zipper, Regular Left Zipper, 21050, 21040
