So far as I am concerned Marmot is the Technical gear leader these days. Before I would have told you this was The North Face, but everything Marmot builds or creates is just better. This bag is no different.

I have been using the Marmot Helium bag but wanted a summer bag as well. I thought long and hard about getting a down summer bag. The Helium I use in below freezing temps, so not too much to worry about with water soaking the down. The Atom will be used in rain storms so you better have a good tent that’s going to stay dry if you use this bag.

This bag is everything as advertised. It's as roomy as the Helium (I'm 6’1" and 240 lbs) and I am very comfortable in the long version Atom. This thing packs down to nothingness so much so I have been able to downsize my backpack. The room that is normally reserved for sleeping bags of the past is now used for other stuff. As a result I just don’t need as much room. Temperature rating is again understated if anything. A pair of long johns, a cap, and I think I'd be happy down to 25 degress.

The reason that this bag is better then the Helium is because Marmot somehow found a way to drop the price of the bag compared to in the past. The reason it's worse is for some reason Marmot can no longer guarantee 900 fill down.

Great all around bag! Like the other reviewers, I took my Atom down to the mid 30's and was very comfortable. Weighs nothing and extremely comfortable; plenty of room. I'm extremely impressed with this bag, I might just go buy a Helium for those colder nights.

This bag is as promised. I slept comfortable in temps in the mid to lower 30's. This bag also packs down to next to nothing, don't use the stuff sack that comes with it because it's too big, you can go much smaller.
