  • Citing this Editors’ Choice winner, the April 2011 issue of Backpacker claimed, “In the quest for maximum warmth at minimum weight, we have a new standard setter”
  • Filled with certified, super-lofty, ultralight, 900-fill-power goose down (the largest down cluster with the lowest trace of feather) for an unsurpassed warmth-to weight ratio
  • Flow Gate Construction lets you manually shift the down to preferred locations—move it to cold spots, customizing warmth to your personal sleep preference
  • Pertex® Quantum nylon ripstop shell is lightweight and durable, and offers silky softness that enhances the insulation's loft
  • Shell is treated with a Durable Water Repellent finish that causes moisture to bead up and roll off
  • Hood drawcord and insulated collar envelops 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 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
