Marmot Atom Sleeping Bag: 40 Degree Down

Item #MAR1117 | 32 in Stock
5 Star Rating

the mighty Atom!

By Ranked #647 - 55 to 30 Degree Down Bags August 10, 2006

I recently purchased the Marmot Atom to bridge the gap between my REI travel down 45º and my Marmot Helium 15º or Feather Friends Swift 20º epic. At one pound the Atom rocks! I save 13oz from my Helium and over a pound off the Swallow. The REI travel down is actually 8oz heavier than the Atom and likely has more of a 50-55º rating. I have always loved Marmot quality and construction since buying my first Pinnacle 0º in 1992, which by the way is still in near-perfect condition after hundreds of nights. The Atom is built with the best materials and down available. The construction is top notch. I particularly like the hood design which wraps your face with a comfy baffle. At 40º this is a warm, roomy and cozy bag. You could easily push the frost level with a light layer of clothing worn inside. I recently used the Atom at 6,500ft on Mt. Hood on a summer hike. The weather was warm, but it dropped into the low 50's or upper 40's at night. We were at snow level and pitched my tent right next to the slowly fading snow field, which added to the coolness of the night. I was quite happy in my red cocoon. The color is great and adds to a warm tent glow. At one pound I would be hard-pressed to find a better bag! Thanks Marmot!
