Micron 30 Sleeping Bag: 30F Down

Best for 3-season camping and backpacking, the Marmot Micron 30 Sleeping Bag provides reliable insulation with its hydrophobic down. Down provides the best packability and warmth for the weight but can lose its insulating loft if it gets wet. The Micron 30 solves that problem by treating the 650-fill duck down with a DWR treatment to make the down water-resistant. The anatomical mummy cut provides efficient insulation and cuts down our pack weight, and a second zipper adds ventilation options for warm summer nights. We find this sleeping bag comfortable down to frosty temperatures in the upper 30s.
