Backpacker April '08 proclaims the Marmot Atom bag is ''sleep-anywhere evidence that luxury and lightweight can go hand in hand.''

  • One of the sweetest, lightest bags out there, this Marmot masterpiece is for fast, light summer trips.
  • Lightforce nylon shell is lightweight yet strong; a Durable Water Repellent finish causes moisture to bead up and roll off
  • Premium-quality 850-fill-power goose down is extremely compressible and offers an exceptional warmth-to-weight ratio
  • Face muff allows hood to be cinched snug without digging into your face
  • Down-insulated draft tube backs full-length zipper to keep the cold out
  • Zipper guards prevent zipper snags; locking zippers keep bag from opening if you toss and turn at night
  • Classic trapezoidal foot box lets your feet move freely and comfortably, and allows goose down to loft fully to keep your toes toasty warm
  • Stuff sack and storage sack included

Imported.

    Comments about Marmot Atom +40 Sleeping Bag - Regular:

    I have owned the Atom (older model, 900 down, Pertex Quantum version) for almost 4 years. Temps ranged from 36 degrees F to the 80s, on around two dozen trips including some so-cal sections of the PCT. My bag weighed in at an even 18oz., for the version I had, after a dryer run.First and foremost, Marmot, along with other top-quality bags in the industry, i.e. Western Mountaineering, is as close as it gets to achieving indicated temp ratings. They are in the middle of the EN13357 scale and are most comfortable at around 10 degrees warmer than rated, but with a light base layer, they will be comfortable at their ratings.The bag is top quality with perfect stitching, ample room for layering, and a great draft tube that is stuffed with plenty of down. In temps below 40, I wore a med-weight fleece layer and was cozy all night. The zipper is mostly snag-less, but will if the bag is bunched up when you zip it up.I sleep very hot when I get to bed and by 2am, I am a sleep very cold. So, i.e. when I hit the bag at hiker midnight, at 50 degrees, I have the top half of me sticking out of the bag. By 2am, I am snuggled deep in my cocoon with the hood synched.[...]

    Comments about Marmot Atom +40 Sleeping Bag - Regular:

    Will use it when my EQ 15 is just too warm.

    Very comfortable for cool weather.

    Packs light and easily.

    So far my two best packs are Marmots
