Marmot sent us their award-winning Plasma Sleeping Bag to try out. We put it through a number of scientific and rigorous tests to see how the bag performed.
No.1 Sweatbox Test
The Plasma's vertical baffling efficiently transfers body heat from your core to your extremities. In the name of science, we decided to take it a step further with our Sweatbox Test. Enclosed in the bag, the participant was exposed to a temperature of 87°F (30.5°C) for a prolonged period of time. The test yielded a significant loss of body mass due to excessive perspiration. The Plasma bag comes in 40°, 30°, 15° and also 0° for the most extreme conditions.
No. 2 Hide and Seek Test
Next we tested the Plasma bag's outer face fabric for its camouflaging properties. The results were conclusive. Not only is the bag's Pertex© Quantum® face fabric breathable, water-repellant, and rip resistant, but it also very effective as a disguise for a rousing game of Hide and Seek.
No.3 Fish Bowl Test
Upon observation of the Plasma Bag's premium 900 fill down, we hypothesized that it would be able to compress down very small. We conducted the Fish Bowl Test, since as you know, the standard fish bowl is comparable to the size of a stuff sack. We found that, with minimal effort, the Plasma bag compacted down and fit quite nicely into our fish bowl. Not only does the Plasma's down-fill pack well, the whole bag weighs under 2 lbs.
Bottom line, if you're looking for the best warmth-to-weight ratio in a hide and seek bag, we're officially recommending the Marmot Plasma.
