- With a European Norm (EN) lower-limit rating of 5.5°F, the Plasma 0 sleeping bag is suitable for 4-season use when temperatures dip into single digits
- Filled with certified, super-lofty, ultralight, 875-fill-power goose down (the largest down cluster with the lowest trace of feather) for an unsurpassed warmth-to weight ratio
- Down is treated to resist moisture to maintain warmth; treated down stays drier 10 times longer, maintains 150% more loft and dries 30% faster than untreated down
- Pertex® Quantum nylon ripstop shell is lightweight, durable and silky soft
- Shell is treated with a durable water repellent finish that causes moisture to bead up and roll off
- Hood drawcord and insulated collar envelop your head and shoulders in warmth; down gasket face muff lets you cinch the hood snug without it digging into your face
- Vertical baffles prevent cold spots by keeping the goose down fully lofted and in place
- Down-insulated draft tube backs the 2-way, full-length zipper to keep the cold out
- Wrap-around footbox construction reduces down compression; Flow design with the classic trapezoidal foot box shape lets feet move freely and keeps down lofted for warmth
- Zipper guard runs the entire length of the draft tube to prevent fabric from getting caught in zipper
- Marmot Plasma 0 Sleeping Bag features an ultralight stuff sack and storage bag
- European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags
Imported.
Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.
