Description

Ultralight, thermally efficient, and super-packable.

Winner of multiple awards including Outside Magazine's prestigious "Gear of the Year," the Marmot Plasma 40 Sleeping Bag is in a class of its own. What makes this bag so special, you ask? For starters, the folks at Marmot built in an innovative vertical-baffle system that transfers more heat to your extremities while keeping the bag's overall weight silly low. Add in top-shelf materials like 900-fill goose down and Pertex Quantum fabric, and it's easy to see why this bag deserves its place at the apex of the podium.
  • Awards: Outside Magazine's Gear of the Year 2011; Backpacker Magazine Editors' Choice 2011; National Geographic Adventure Gear of the Year 2011
  • EN comfort-rated at 51-degrees F for summer-like conditions; lower-limit-rated at 43.5-degrees F for occasional use during late spring and early fall
  • Ultra-plush, 900-fill goose down is as light as a wisp of fog, as good at rebounding as a seven-foot center, and features one of the highest warmth-to-weight ratios known to humankind
  • Pertex Quantum GL fabric keeps weight to a minimum while maximizing packability and enhancing breathability so that condensation doesn't build up in the down insulation
  • Intosect Flow vertical baffle system reduces weight and transfers heat from the core of your body to your extremities
  • Down-filled draft collar, zipper-length draft tube, and ground-level seams help prevent leaks and improve warmth retention
  • Wrap-around foot box vaults the foot area to prevent the compression of down and extend the bag's comfort range
  • Two hang loops at the foot allow you to easily hang the bag to air it out

Have used this bag a few nights now. When you first get this bag, it is ridiculously light, and you wonder if it will keep you warm at all! But it does well in summer conditions, as it is a summer bag. I used this bag in a grand trunk hammock at about 53 ish degrees in 20-30 mph winds and I was warm in shorts and a tshirt. The fabric is super smooth, and feels nice against the skin. The inner red color is bright. On one night that got down around 40-45 in the fall, I was cold and had to put on an extra down jacket I had. All in all, a great purchase for a lightweight summer bag. Price is pretty steep, and the wispy weight takes a while to begin to trust, but I think it is worth it.
