Here's what other sites are saying:

Marmot's Plasma 40 features: Incredibly lightweight Pertex fabric that forms a water-resistant, breathable barrier against the elements, 900+ fill-power goose down and Flow Gate Construction that allows warm air to circulate without allowing the down to shift.


The lightest weight bag in the 900-fill power down Plasma Series, the ultralight, ultrapackable Plasma +40 Down Bag is tailor made for the fast and light route. The unique Insotect Flow Vertical Baffle System reduces weight and transfers heat from the core of your body to your extremities.

If you're the dude who cuts his toothbrush in half, shaves his legs, and pulls out all his teeth to save weight before going backpacking, odds are you'll fall in love with the Marmot Plasma 40-Degree Down Sleeping Bag. It's pretty much a one-season bag (mild spring and fall nights will be OK, too), but good gravy, is it light and packable--does 1lb 2oz float your boat' The Plasma's able to be so minimal because it packs super-high loft 875-fill down into a Pertex Quantum shell, which is extremely durable but still light as a feather, and uses Insotect Flow vertical baffles to direct heat to your extremities. In that way it keeps your feet warm without the need for more down, which would just take up space in your pack. If it's not enough that the Plasma would pack into your water bottle, its down is treated with Down Defender to improve its water-resistance, and the bag's exterior has a DWR coating to shed water and keep the insulation functioning with optimum efficiency. It also has a litany of desirable features, like an insulated draft tube and collar, two-way zippers with garages, and a soft face muff to seal out drafts around your mug. Hang it up using the loops, store it in a loose sack to keep the down lofted, and you'll have ultralight summer insulation for years.


Travel fast on your warm-weather backpacking trips with the featherlight Marmot Plasma 40 Sleeping Bag. It weighs in at only 1 lb. 3 oz. (regular length) and provides warmth down to about 40degF.
