Awesome bag. Extremely light. My pack feels better knowing I have an atom in there. Compresses very small. Takes up hardly any room

Comments about Atom 40 Sleeping Bag (850 Down):

I just completed an 8-day hut to hut Presidential Range hike in the White Mountains NH with this bag. It compresses into a size that is only slight bigger than a silk sack and provides more warmth for the cold huts we encountered. It was a like sleeping in a cloud. I can't think of anything wrong with it. Zipper zipped, the hood stayed in place, and I was never cold - what more can you ask from a summer bag.

Questions & Answers

Q & A For The Marmot Atom 40 Sleeping Bag (850 Down)

Technology Used In The Atom 40 Sleeping Bag (850 Down)

Baffled Construction

Baffles are chambers created between the outer shell and inner liner of a sleeping bag or jacket. These chambers hold the insulation and create an even distribution, preventing unwanted grouping of insulation. There are different types of baffles. A "stitched-through" baffle joins the outer shell and inner liner together by means of direct stitching. Heat loss through seams is a disadvantage of the stitched through baffle. Optimal warmth is achieved through the use of a "box wall" style baffle. This method uses additional material between the outer and inner materials to create a wall that unites the two layers and creates a slightly larger and more uniform baffle. Different variations on the box wall positioning create a variety of advanced baffle systems.

Down Insulation

Water foul, like geese and duck, actually provide one of the most efficient forms of insulation available. Down is the light, fluffy undercoating at the base of the feathers of waterfowl. Down is a multi-dimensional structure that insulates by creating pockets of still air that retain body heat. Down is highly breathable and exceptionally comfortable. It is longer lasting and much more compressible than synthetic insulation. A disadvantage of down insulation is its loss of efficiency in wet conditions. It will also take much longer to dry than a synthetic insulation. Down is available in different fill powers. Fill power is defined by the amount of loft that is gained under loft test conditions. The higher the fill power number the greater the loft and the greater the performance of the down insulation. Fill powers may range from 500 fill to 900+ fill power.
