The Mythic 400 is an exceptional choice for ultra-light mountain endeavours. Clocking in at just 660 grams yet offering solid three-season performance, its impressive stats are a result of premium materials and precision design combined. The thermal efficiency of the 900-fill hydrophobic down is enhanced through the trapezoidal baffles of the box wall construction, resulting in a warm yet light and compressible sleeping bag. When you need to cut weight without sacrificing comfort on your next mountain mission, be sure to choose the Mythic.
