  • With a European Norm (EN) lower-limit rating of 18°F, the Plasma 15 sleeping bag is suitable for 3-season use and occasional winter outings
  • 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 two-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 15 Sleeping Bag features an ultralight stuff sack and storage bag
