Sam D.wrote a review of Marmot Atom Sleeping Bag: 40 Degree Down on March 25, 2011
I did a lot of research to find the right sleeping bag for 30-50 degree nights. I narrowed it down to the Marmot Atom and Big Agnes Horse Thief. I had trouble deciding which to get so I got them both so my wife would have one. My wife and I were both cold all night in the Horse Thief, which I returned because it was badly over rated and over priced for the way it performed. I really liked the design and wanted it to work but you cant sleep shivering. The Atom performed better than expected. I slept comfortable in a 1-person tent on nights of 30 and 33 degrees with long underwear. Very comfortable and packs easily to near nothing without a compression sack. It warms up instantly and is so light you can not feel the bag on you. Good product!
