The Rab Mythic G Jacket features featherlight performance and ground-breaking 1000 fill power goose down for ridiculous warmth for the weight and premium packability. Rab has paired that light and lofty down with a heat-reflective TILT lining to hold in as much heat as possible while keeping the jacket's weight below 9 ounces. The articulated sleeves increase mobility for climbing and skiing while an adjustable hem and elasticated cuffs seal out snow and keep things trim for better breathability and heat retention. These features add up to a high performance puffy that's both ultralight and ultrawarm.
