Rarely do we ever consider the invisible world that exists all around us on the microscopic level. These organisms and particles are so small that scientists work with a unit of measurement that’s so small it’s one millionth of a meter: the micron. You certainly don’t need a microscope to see the Mircon 40° Sleeping Bag from Marmot, but its added weight is light enough you may not notice it at all.

Light as a feather, the Micron 40° weighs just over a pound, filled with duck down for insulation that provides exceptional warmth as well as compressibility. It's perfect for summer camp trips when saving space and cutting back on weight is crucial. The down is also treated with Down Defender, a water-resistant treatment that ensures the insulation stays dry and maintains its loft, even in damp conditions!

The footbox and hood maximize warmth and comfort, while the smooth-curved baffle construction reduces cold spots. The full-length YKK two-way zipper with an anti-snag slider ensures easy entry and exit, and the zipper garage provides added comfort by eliminating drafts and chafing. Choose the Marmot Micron 40° Sleeping Bag for your next warm-weather adventure and keep things light!
